Connect ammeter to (+) TB1-15, (-) TB1-16.
Press enter.
To trim 0mA analog output: Press CLEAR to
enable editing and enter a small negative
number (i.e. -0.100) to force a display reading,
then clear and enter small quantity measured
on your meter.
The display will return to Calibrate 0mA out.
Press the down arrow key to advance to the
20mA analog out or repeat above if necessary.
Connect ammeter to (+) TB1-15, (-) TB1-16.
Press enter.
To trim 20mA analog output: Press CLEAR to
enable editing and enter the current reading
that is on the ammeter display. Press enter.
The display will automatically return to the
Calibrate 20mA Aout submenu. Calibration is

Press the Menu key to go back to Calibrate
top-level menu.
Press enter to test the analog inputs.
To check voltage input accuracy: Use TB1-4
as Reference Ground, input 0-10 Volts to TB1-
5. Display should show voltage being input.
Use voltage meter to verify input.
To check current input accuracy: Use TB1-4
as Reference Ground, input 0-20mA to TB1-7
and/or TB1-8. Display should show current
being input. Use ammeter to verify input.
To check RTD input accuracy: Connect a
jumper wire between TB1-6 and TB1-7, Place
a 100 ohm 0.1% resistor between TB1-7 and
TB1-8. Display should show 100 ohms
±0.1%.
