The Only Process Meter You Will Ever Need
Front, back and in between, the ProVu meter boasts specifications, features and functionality that make it the only 1/8 DIN process meter you will ever need. The number one feature that makes the ProVu such a useful device is its built-in 24 VDC power supply to drive the transmitter as illustrated by the above diagram. This feature not only saves the cost of an external power supply, but also greatly simplifies wiring. In addition, there is a second 40 mA power supply provided with the 4-20 mA output option, evident also in the above diagram.
The picture above illustrates several other reasons why the ProVu is the only process meter you will ever need. First off, is the NEMA 4X rated front panel which means you can install the ProVu in panels exposed to moisture, dust and other adverse conditions. The picture also points out that the ProVu is available with an optional Sunbright display which means you can install and read the ProVu in direct sunlight. The next thing to notice is the 6-digit dual-line display that can display numbers up to 999,999 on the upper line and show either a tag or the input in a different scale on the lower line.
Other key features include four relays and 4-20 mA output option, advanced signal input conditioning like automatic round horizontal tank linearization, function keys, pump alternation capability, and Modbus RTU serial communications. Finally all these features and capabilities can easily be programmed with free MeterView Pro PC-based software.

Isolated Transmitter Power Supplies
24 V @ 200 mA Transmitter Power Supply
One of the most useful standard features of the AC powered PD6000 is its built-in isolated, 24 V @ 200 mA power supply to power the transmitter. This feature saves money by eliminating an external power supply and also simplifies wiring by reducing the number of devices in the loop. It can be configured for 5, 10, or 24 V (default) by means of a simple internal jumper. This power supply is even available on meters that are powered from DC power (24 V @ 100 mA). To use an external power supply instead of the internal power supply, simply make connections to different terminals on the ProVu. The following diagrams illustrate how to wire the ProVu so it will power the transmitter:
24 V @ 40 mA 4-20 mA Output Power Supply
Not only can the ProVu power the 4-20 mA input signal, but an additional power supply of 24 V @ 40 mA is provided with the 4-20 mA output option to power the 4-20 mA output.
Resettable Fuse Prevents Current Overload
Another very useful aspect of the ProVu is that the current input is protected against current overload by a resettable fuse. The fuse limits the current to a safe level when it detects a fault condition, and automatically resets itself when the fault condition is removed.
Other Uses for the Transmitter Power Supplies
The most common use for these two power supplies is for the 200 mA transmitter power supply to power the field transmitter and 40 mA power supply to power the 4-20 mA output from the meter. However, since these two power supplies are isolated they can be used in other ways. For instance, some level transmitters require the use of a heated lens. The ProVu’s 200 mA power supply could be used to power the heated lens and ProVu’s 40 mA power supply could be used to power the 4-20 mA input.
ProVu Powers Both Heater and 4-20 Output
External Power Supply for the Loop
For applications that require an external transmitter power supply, the same ProVu is used and merely wired in a different fashion as the following diagrams illustrate:
PDA1024-01 24 VDC Transmitter Power Supply
Precision Digital offers the PDA1024-01 for applications that require more than the 200 mA power that the ProVu can provide.
Output Voltage: 24 VDC ±10% @ 1.5A rated current
Dimensions: 3.07" x 3.66" x 2.20" (78 mm x 93 mm x 56 mm) (W x H x D)
Advanced Display Features
Dual-Line Makes All the Difference
The upper display can be programmed to indicate PV, maximum (peak), minimum (valley), alternating maximum/ minimum, one of eight alarm set points, or Modbus input. The lower display can be configured to display engineering units, set points, user defined messages, or simply turned off.
The ProVu’s dual-line display makes all the difference both when programming the instrument and when using it in the field. When programming the instrument, the dual line display prompts for the needed information and also helps you keep track of where you are in the setup process. When using the instrument, the dual line display provides more information such as displaying the input in two different scales like height and volume for a level application. We call this the Dual-Scale feature.
The ProVu’s dual-line display makes programming the instrument much easier because the lower line prompts for the needed information and also helps you keep track of where you are in the setup process.
The ProVu is prompting for the value for Input 2 and displaying the default value of 20.00 mA. The “2” in 20.00 is brighter than the rest of the digits indicating that it is the number that will be changed by the Up and Right arrows.
The ProVu is now prompting for what the user wants Display 2 to be; that is the value that corresponds to 20 mA. In this case Display 2 is currently set to 95.00.
Bright & Optional Super-Bright Display
The standard ProVu’s display is bright enough for most applications, including moderate sun exposure. However, for direct sunlight exposure the ProVu is available with super-bright LEDs that make it possible to read the ProVu even in direct sunlight. Both versions of the ProVu have eight levels of adjustable intensity.
Rounding Feature for Even Steadier Display
The rounding feature is used to give the user a steadier display with fluctuating signals. It causes the display to round to the nearest value according to the rounding value selected (1, 2, 5, 10, 20, 50, or 100). For example, with a rounding value of 10, and an input of 12346, the display would indicate 12350.
Dual-Scale Display Feature
The PROVU PD6000 has a rather unique, and very flexible dual-scale capability. This is of particular value in level applications where a second scaled display can represent the measured input in a different form (i.e. gallons & height). Both displays are independently scaled and are based on the 4-20 mA input signal. Beyond level, this function has been used for pressure & force, current & power, feet & meters, GPM & CFM, and more.
MeterView Pro can be used to program the ProVu to display the input in two different scales:
Toggling Between Reading & Units with Tag
The ProVu can also be programmed so the upper line toggles between the reading and units and the lower line displays a tag. For instance, the upper line toggles between 9500 and Gal and the lower line displays Tank 1.
Other Uses for Lower Line
The lower line can also be used indicate units, a tag, or even a setpoint as the following pictures illustrate:Back to top
Quick & Easy Scale & Programming Methods
The ProVu can be programmed either via the front panel push buttons or free, PC-based MeterView Pro software. MeterView Pro is resident on the ProVu and is accessed by a provided USB cable, so it is by far the easiest way to program the ProVu. The ProVu can be calibrated either by applying a known signal or scaled by entering a desired value with the front panel buttons or MeterView Pro software. Most customers will use the scaling method because it is simpler and does not require a calibrated signal source. Selecting the input to be current or voltage is done with the front panel buttons or MeterView Pro software. Once programming is completed it can be locked with a password.
Free PC-Based MeterView Pro USB Programming Software & Cable
The ProVu comes preloaded with free MeterView Pro programming software that connects and installs directly to your PC with a standard USB cable, also provided free with each instrument. This eliminates the need to insert CDs, install drivers, or download software from the internet. When you connect your ProVu to your PC, MeterView Pro is downloaded to your PC, the software automatically selects the model you are programming, and you’re ready to start programming immediately. Further simplifying the programming process, the ProVu can be powered from the USB port, so no need to apply external power while programming your meter. In addition to programming, the software will also allow you to monitor, and datalog a ProVu using your PC. You can also generate and save programming files for later use.

4-20 mA Output & Relays
4-20 mA Analog Output
The isolated analog retransmission signal can be configured to represent the process variable (PV), maximum (peak) value, minimum (valley) value, the value for any of the eight relay set points, or Modbus input. While the output is nominally 4-20 mA, the signal will accurately accommodate under- and over-ranges from 1 to 23 mA.
The 4-20 mA output can be reversed scaled such that 4 mA represents the high value and 20 mA represents the low value. For instance, a 4-20 mA output signal could be generated as the meter went from 100.0 to 0.0.
For applications where the input was linearized by the ProVu, the 4-20 mA output will represent that linearized value.
The ProVu can provide 40 mA at 24 VDC to power the 4-20 mA output signal or an external power supply can be used:
The internal 24 VDC power supply powering the analog output may be used to power other devices, if the analog output is not used. The I+ terminal is the +24 V and the R terminal is the return.
The 4-20 mA output can either be programmed using the front panel push buttons or free MeterView Pro software.
Front Panel Push Button Programming
The 4-20 mA analog output can be scaled to provide a 4-20 mA signal for any display range selected. No equipment is needed to scale the analog output; simply program the display values to the corresponding mA output signal. The Analog Output menu is used to program the 4-20 mA output based on display values.

Min: Minimum analog output value allowed regardless of input
Relays for Alarm & Control Applications
Adding relays to the ProVu meter turns it into a sophisticated alarm device as well as a powerful, yet simple, alternative to a more complicated PLC system for control applications. One such application would be pump control using the ProVu’s relays in pump alternation mode. The ProVu can be equipped with up to four 3 A Form C (SPDT) internal relays and an additional four more 3 A Form A (SPST) external relays. Relays are highly user-configurable as the following screen shot from MeterView Pro indicates:
Setting Set and Reset Points (HI / LO Alarms)
All relays are independent of each other and may be programmed as high or low alarms with user desired set and reset points. Setting a set point above a reset point results in a high alarm and setting a set point below a reset point results in a low alarm. Alarms have 0 – 100% deadband and set and reset points may be set anywhere in the range of the meter.
Resetting the Relays (Action in MV Pro)
All relays are independent of each other and may be programmed to reset (Action in MV Pro) in the following ways:
- Automatic: Alarm will reset automatically once the alarm condition has cleared.
- Automatic/Manual: Alarm will reset automatically once the alarm condition has cleared but can also be reset using the F3 front panel button* at any time.
- Latching: Alarm must be reset manually and can be done so at any time. Press the F3 front panel button* at any time to clear the alarm.
- Latching with Reset after Cleared: Alarm must be reset manually and can only be done so after the alarm condition has cleared. Press the F3 front panel button* after the alarm condition has cleared to reset the alarm.
* Or by connecting an external switch to F4 terminal or with an optional digital input.
Time Delay (On and Off)
In many applications it is desirable to wait before turning off or on a relay – such as waiting for a process to settle before taking action. Each relay on the ProVu can be programmed with independent on and off time delays of 0 to 999.9 seconds to achieve this.
Relays Auto Initialization
When power is applied to the meter, the front panel LEDs and alarm relays will reflect the state of the input to the meter.
Signal Loss or Loop Break Relay Operation
When the meter detects a break in the 4-20 mA loop, the relay will go to one of the following selected actions:
- Turn On (Go to alarm condition)
- Turn Off (Go to non-alarm condition)
- Ignore (Processed as a low signal condition)
User Selectable Fail-Safe Operation
All relays are independent of each other and may be programmed for user selectable fail-safe operation. With the fail-safe feature activated, the relays will transfer to the alarm state on power loss to the meter.
Front Panel LEDs
The meter is supplied with four alarm points that include front panel LEDs to indicate alarm conditions. This standard feature is particularly useful for alarm applications that require visual-only indication.
Manual Output Control
Take control of any output with this feature. All relays can be forced ON or OFF, and the 4-20 mA output signal can be set to any value within its range. When the relays and 4-20 mA output are controlled manually, an LED labeled “M” is turned on and the associated Alarm LEDs (1-8) flash every 10 seconds indicating that the meter is in manual control mode.
Sampling Function (PV Triggered Timed Relay)
The sampling function allows the operator to set a relay as a “sampling” relay. When the PV reaches that set point, it will close that relay’s contacts for a preset period of time (0.1 to 5999.9 seconds). An example of its use may be for beer/ ale fermentation. When the batch reaches a certain pH, the relay contacts would close and by some means (light, horn, etc.) alert someone to take a sample, or provide the trigger to automatically take a sample of the batch. The utility of this function can, of course, be expanded beyond sampling and be used whenever a timed relay output closure is required when the PV reaches a certain set point.
This function allows a process to use one or more very low voltage input signals or simple switch contacts to control the state of one or more internal “interlock” relays. A violation (i.e. loss of input, open switch, or open circuit) forces one or more N/O interlock relay contacts to open. One input can be used in series with a number of interlock switches, or up to eight inputs can be required to force-on one (or more) internal interlock relays. Requires PDA1044 Digital I/O module or use of on-board digital input F4. Please see ProVu Series Safety Interlock Feature whitepaper on our website for more information.
Switching Inductive Loads
The use of suppressors (snubbers) is strongly recommended when switching inductive loads to prevent disrupting the microprocessor’s operation. The suppressors also prolong the life of the relay contacts. Precision Digital offers the PDX6901.
The ProVu can be used as a pump controller when combined with a continuous level transmitter. The most common pump control application is shown below: controlling and alternating two pumps and providing high and low-level alarms. The light / horn accessory can be added to provide visual and audible alarm indication.
Signal Input Conditioning
There are many applications in the industrial world that can’t be satisfied with simple, two-point linear scaling so the ProVu has advanced linearization capabilities to handle applications like round horizontal tank volume measurement, open channel flow, DP flow, and others. And all of these capabilities are easily programmed using MeterView Pro programming software.
The most common way to linearize a non-linear signal is to break it up into smaller ranges that are more linear than the overall range. The ProVu is available with up to 32 points of linearization and if dual scale feature is used, the second PV can have up to eight points of linearization. The linearization data can be imported from an Excel spreadsheet or can be exported from MeterView Pro to an Excel spreadsheet. The following screen shot from MeterView Pro shows PV1 with 9 points of linearization and PV 2 with 5 points of linearization:
Specialized Linearization Functions
In addition to the generic 32- and 8-point linearization functions, the ProVu is also available with specialized functions for round horizontal tanks, open channel flow, and DP flow.
Round Horizontal Tank
Square Root Extraction
The user enters the diameter and length of a flat-ended round horizontal tank resulting in a display of volume.
The input is raised to an exponent programmable by the user resulting in a display of open channel flow rate.
The square root of the input is taken resulting in a display of flow rate.
Round Horizontal Tank Volume Linearizer
In this application, a level sensor is measuring the height in the round horizontal tank and the ProVu is converting that signal to volume using the RHT function. All the user has to do is input the diameter and length of the tank and the meter converts the signal to volume.
DP Flow via Square Root Extraction
In this application, the PD6000 is displaying flow rate by extracting the square root from the 4-20 mA signal from a differential pressure transmitter. The user selectable low-flow cutoff feature gives a reading of zero when the flow rate drops below a user selectable value.
Linear 4-20 mA Analog Output
For applications where the input was linearized by the ProVu, the 4-20 mA output will represent that linearized value.
Open Channel Flow Rate Indication
In this application, a level sensor is measuring the height in a weir and the ProVu is converting that signal to flow rate using the programmable exponent function. All the user has to do is input the corresponding exponent for their weir and the meter will convert the signal to flow.
The following information is required for programming the PD6000 for open channel flow rate:
- The exponent value associated with the flow calculation for the specific weir or flume being used.
- The zero head, or water depth, mA value from the level transmitter.
- The mA value from the transmitter for the maximum head, and the flow rate at that level. The level transmitter is normally programmed to provide 20 mA at the maximum head value and flow rate.

Modbus® RTU Serial Communications
With the purchase of a serial communication adapter, PROVU meters can communicate with any Modbus Master device using the ever-popular Modbus communications protocol that is included in every PROVU. In addition to the typical Modbus capabilities of reading PVs and writing set points, below are some examples of other things that can be done with the meter’s Modbus communications:
- Send a 6-character message to lower display upon an event
- Convert a digital value to a 4-20 mA signal
- Remote user control (i.e. change set points, acknowledge alarms)
- Input a Modbus digital PV (in place of analog input)
- Remote override of any or all relays and analog outputs
Serial Communication Devices
Precision Digital provides a variety of serial communication devices to interface the ProVu meter with other devices.
PDA1232 & PDA1485 Communication Modules
Serial communications on the PROVU meter can be added anytime with external PDA1232 (RS-232) or PDA1485 (RS-485) communication adapters. Free Modbus protocol is included for use with the PROVU serial communications modules.

Field Expansion Modules
Add functionality to the PROVU in the field with easy-to-install external expansion modules. Add RS-232 or RS-485 communications, I/O modules (up to 2), and 4-relay expansion module. The menu items for these modules do not appear until the module is connected, simplifying the basic menu. Relay and digital I/O modules are shown below with optional DIN rail mounting kit, P/N PDA1002.
PDA1044 I/O Expansion Module
Four digital inputs and four digital outputs are available per expansion module. The PROVU meter will accept two of these modules. External digital inputs can function similarly to the front panel function keys or on-board digital input F4. They can be configured to trigger certain events (i.e. acknowledge/ reset alarms, reset max and/or min values, disable/enable all output relays, and hold current relay states), provide direct menu access point, or mimic front panel keys. The I/O module can be used to configure the PROVU remotely, in essence giving the user control of the four front panel push buttons. This feature is particularly useful if the meter is mounted inside an explosion-proof enclosure.
Digital outputs can be used to remotely monitor PROVU’s alarm relay output states, or the states of a variety of actions and functions executed by the meter.
PDA1004 Relay Expansion Module
An external module containing four 3 A Form A (SPST) relays can be added to the PROVU at anytime. Removable screw terminal blocks accept 12 to 22 AWG wire.
The ProVu is designed for ease-of-use in industrial applications. Considerations include a NEMA 4X front panel, wide operating temperature range, removable screw terminal connectors, snap in place mounting brackets, forgiving panel cutout requirement, and UL Listing for electrical safety. All of these features are backed by a 3-year warranty.
Type 4X / NEMA 4X Front Panel
Wide Operating Temperature Range
The ProVu can operate from -40 to 65°C (-40 to 150°F) meaning it can be installed in a wide variety of indoor and outdoor industrial applications. And over this range, the ProVu will drift no more than 0.005% of calibrated span/°C max from 0 to 65°C ambient and 0.01% of calibrated span/°C max from -40 to 0°C ambient.
Removable Screw Terminal Connectors
Industrial applications require screw terminal connections for easy field wiring and the ProVu goes one step further in convenience by making them removable also.
Secured-in-Place Rugged Mounting Brackets
If you’re installing the ProVu outdoors in the hot or cold weather, the last thing you want to do is fumble around with mounting brackets that don’t stay in place. The ProVu’s mounting brackets can be easily secured into place and then screwed down to the panel. These brackets are rugged so they can be tightened to the panel to provide a solid NEMA 4X seal.
Forgiving Panel Cutout Requirement
The ProVu’s bezel has been oversized to allow for not perfectly executed panel cutouts where NEMA 4X seal is not required.

Function Keys, F4 Terminal, Digital Inputs
There are three ways the user can interact with the Helios to perform a variety of useful functions:
1. Three Front Panel Function Keys
The default settings for the function keys are:
2. F4 On-Board Digital Input
The PD6000 includes a digital input as standard. This digital input can operate with the tare, reset tare, or interlock relays feature, force relays on from a signal from a PLC or relay on other equipment, and much more. This is ideal for installations where the meter is inaccessible behind a cover, or where an additional function key is needed for customized operation.
The F4 terminal is particularly useful for wiring up a remote switch to reset the relays as shown here:
3. Optional 4 Digital Input/Output Module PDA1044
With these three methods, the ProVu can be programmed to trigger certain events (i.e acknowledge relays, reset max and/or min, disable/enable output relays, or hold current relay states), provide direct menu access points and more.
Function Key, Digital Inputs, & Digital Outputs Descriptions
The following table describes the actions that ProVu function keys and digital inputs can be programmed to perform.

Remote Operation of Front Panel Buttons
The user can operate the front panel buttons from a remote location by using digital inputs programmed in the following manner:
The tare function zero’s out the display. In the case of scale weight, tare is used to eliminate container weight and provide net weight readings. There are two tare functions; Capture Tare and Reset Tare. When the capture tare function is used, the display reading is offset by the displayed amount to make the displayed value zero. This modified display value is the net value. The originally displayed value without the tare offset is the gross value. Both may be chosen as a display option. Reset tare removes the display offset.
Reset tare removes the display offset of the net value, and the gross and net values become the same until a new capture tare is entered.
Max / Min Display
Max/Min (or Peak/Valley) is standard on the ProVu PD6000. Either display can be configured to show either maximum or minimum excursion since last reset. The displays can also be configured to toggle between Max and Min values. Both values can be simply reset from the front panel.
MeterView Pro Monitoring & Datalogging Software
Not only does free MeterView Pro software greatly simplify setup and programming of the ProVu, it can also be used to monitor and datalog your process.
- Custom Tags: i.e. Tank Level Volume
- Custom Units: i.e. Gallons, Feet, Percent
- Alarm Status Indicators
Collected data logger information can be sent to a CSV file for importing into a spreadsheet program. Below is an example of one such file. Of course, once within the spreadsheet, much can be done to customize the data.
Relays can be controlled from MeterView Pro for testing purposes. This is commonly done to determine whether the relays are functioning properly. In the Setup window, under Relay and Digital Out Test you have the option of selecting the relays you want in an ON state or OFF state and also whether you want to leave the relays in manual control or to return them to automatic operation.
Four-Position Control Station for Remote Operation of ProVu Buttons
The PD6000's four programming and operations buttons can be remotely controlled by using the PDA2364-MRUE 4-button control station accessory as shown in the diagram below.
Plastic Control Stations For The ProVu PD6000
The PDA2360 series of plastic control stations provide a convenient way to remotely control devices such as Precision Digital’s ProVu PD6000. The PDA2364-MRUE four-position control station mimics the ProVu’s four front panel buttons: Menu, Right Arrow, Up Arrow, and Enter. The PDA2360-E is an emergency stop button, the PDA2361-A is used to acknowledge an alarm, and the PDA2361-Q is to silence an alarm.

NEMA 4 & 4X Field Enclosures
Precision Digital offers a variety of rugged enclosures that provide a high degree of protection against harsh operating environments. Thermoplastic and stainless steel NEMA 4X, and painted steel NEMA 4 enclosures for up to 10 ProVu meters are available. In addition, Precision Digital offers a Light / Horn that can be mounted to most of these enclosures to provide visual and audible indication of alarms. Many enclosures also have sufficient space to house Precision Digital’s model PDA1024-01 24 V power supply to provide power to transmitters and sensors that require more than the 200 mA that the ProVu can provide.

Light / Horn & Reset Button Mounted to Enclosure
ProVu Meter in a PDA2301 Enclosure with MOD-LH Light / Horn and Reset Button. Enclosure & MOD-LH Sold Separately. Assembly Required.
Precision Digital offers a wide variety of NEMA 4 and NEMA 4X enclosures that can be equipped with MOD-LH Light / Horn and Reset Button. When MOD-LH is ordered, the accompanying enclosure on the order comes with the holes pre-drilled for the Light / Horn and the Reset Button and the user performs the mounting and wiring. Meter and enclosure are sold separately. The Light / Horn and the Reset Button can also be ordered as separate items and the user performs all hole-drilling, mounting and wiring as desired. The light and horn can be controlled independently of each other via separate relays on the ProVu meter; and since the meter's relays can be reset in a variety of ways, there are several ways the Light / Horn option can operate. For instance, the horn can be programmed to silence at any time via the Reset Button or F3 front panel button on the ProVu, and light to reset automatically when the alarm clears as the following table illustrates:
|Relay #||Connected to||Typical reset method (user selectable)|
|1||Flashing Light(1)||Auto reset|
|2||Horn||Silence with Reset Button at any time|
|3||User Device||As user desires|
|4||User Device||As user desires|
1. Light can be wired to flash or stay steady on
Note: The Light / Horn accessory is powered from the 200 mA transmitter power supply; so when it is installed, there is less power available for the transmitter. See Transmitter Power Supply specification in MOD-LH manual for details.
