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
mA 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
OHMS jumper wire between TB1-6 and TB1-7, Place
00.000 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
