EASY SETUP AND PROGRAMMING

The Javelin D is easy to set up and program because everything is done using the simple four-button programming method. There are no jumpers, and no need to ever open the case. After completing setup of one meter, additional meters can be “cloned” using the time-saving Copy function.


Front Panel Buttons

User Friendly Menu Structure

To simplify programming, the Javelin’s setup functions are divided into two menus. A main menu handles all the basic setup functions.
An advanced features menu handles the special functions not commonly used.
  • Press the Menu button to enter or exit the Programming Mode at any time.
  • Press the Right arrow button to move to the next digit during digit programming.
  • Press the Up arrow button to scroll through the menus, decimal point, or to increment the value of a digit.
  • Press the Enter/Ack button to access a menu, accept a setting, or to acknowledge relays.

Main Menu

The main menu consists of the three most commonly used functions: Setup, Program, and Password. Press the Menu button to enter the Programming Mode then press the Up arrow button to scroll main menu.

The Setup menu is used to select the input signal, °F or °C, and relay setup. The Program menu is used to calibrate the meter.

The display moves to the next menu after the Enter/ACK button is pressed.

Advanced Features Menu

To simplify the setup process, the least used features in most applications are located in the Advanced Features menu.

To access the Advanced Features menu, press and hold the Right arrow button first and then press and hold the Menu button for three seconds.


DC Voltage Digital Panel Meter, Advanced Menu Features

Noise Filter (Digital Panel meters, Advanced Menu Function,  Filter)

This function averages any minor or quick changes in the input signal and displays the reading with greater stability.

Noise Filter Bypass (Digital Panel meters, Advanced Menu Function,  Noiise bypass)

The meter can be programmed to filter small input changes (with noise filter function), but allow larger input changes to be displayed immediately by setting the noise filter bypass function accordingly. If the change in input signal exceeds the bypass value, no filtering will occur and the new value will be displayed immediately.

Serial Communication (Digital Panel meters, Advanced Menu Function,  Serial)

This menu is used to program the Serial communication parameters such as the address for each meter when used in a multi-drop mode.

The meter is equipped with serial communications capability as a standard feature using PDC Serial Communication Protocol. The Modbus RTU Protocol is optional and can be purchased at any time.

Click here for more information on serial communications.

Protocol Selection Menu (Digital Panel meters, Advanced Menu Function,  Protocal Selection)

The Protocol selection menu is used to select either the PDC or the Modbus protocol. If Modbus option is purchased separately, it is necessary to enter a four-digit code to permenantly enable the Modbus protocol.

Meter Copy (Digital Panel meters, Advanced Menu Function,  Meter Copy)

The Copy function is used to copy (or clone) all the settings from one Javelin D meter to other Javelin D meters in less than 5 seconds!

The Copy function is a standard feature on all meters. and does not require a serial communication adapter.

Select Menu (Digital Panel meters, Advanced Menu Function,  Select Menu)

The Select menu is used to select linear or square root function, display intensity, and low-flow cutoff. Selection for relay or analog output is a factory setting depending on the option installed.

Display Intensity Menu (Digital Panel meters, Advanced Menu Function,  Diplay Intesnsity)

The Display Intensity function allows the selection of eight user selectable levels of intensity to help compensate for various lighting conditions, including direct sunlight.

Diagnostic Menu (Digital Panel meters, Advanced Menu Function,  Diagnostic Menu)

The Diagnostic function aids in troubleshooting by providing a convenient way to review setup and programming parameters.

 

VERSATILE OPERATION

The Javelin Max/Min function, two relays, and serial communication options provide all the utility you need to handle all the common applications.

Powerful Relay Functionality

All relay functions are set up from the front panel.
  • Automatic reset only
  • Automatic or manual reset
  • Latching or non-latching relays
  • Alternation control
  • On and off time delays from 0 to 199 seconds
  • Fail-safe operation is user selectable

Maximum/Minimum Readings

To display the maximum and minimum readings since the last reset/power-up, use the MAX button.
