Description

Trim Digital-Analog-Converter (DAC):

These are factory set parameters used to provide an accurate 4.000mA and 20.000mA. This parameter should not be changed as Magtech uses NIST traceable equipment to calibrate our transmitters and only accredited laboratories for the annual calibration of our equipment. This menu will allow the user to change the accuracy of the transmitter output.

A current meter should be used to monitor

the 4/20mA when this function is selected.

Test Loop:

This function allows for direct control of the Transmitter’s current output (mA) capability. Simply enter into this menu and change the current (mA) output as desired. This option is excellent for plant startup verification.

Exit:

This signifies the last menu before the main screen. If the user desires go back through the configuration menus then change the “Yes” to “No” and review the configuration again else press enter while the screen shows “Yes” and return to the main screen.
