Analog In Test
Connect ammeter to (+) TB1-15, (-) TB1-16. Press enter.
To trim 0mA 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 Cal. 20mA out or repeat above if
necessary.
Connect ammeter to (+) TB1-15, (-) TB1-16. Press enter.
To trim 20mA 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 out
submenu. Calibration is complete.
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 TB1-2 and/or 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 TB1-3 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%.
Press Menu key to return to Analog In Test top-level menu.
