OHMS INPUT
1. In OHMS INPUT mode, the unit will display “C 15” for 1 second and then display
the OHMS input using the default calibration.
2. Connect the test leads from the 5520 main Jacks to the 712 jacks in 4 wire
configuration (2 wires at 5520, 4 wires at 712). The unit should read 15.0 Ω ±5%.
3. Push
to go to the next calibration point. “C 400” will be displayed for 1 second
and then it will display the ohms input.
4. Source 400 Ω from the 5520. The unit should read 400.0 Ω ±5%.
5. Push
to go to the next calibration point. “C3200” will be displayed for 1 second
and then it will display the ohms input.
6. Source 3200 Ω from the 5520. The unit should read 3200.0Ω ±5%.
7. Push
to complete OHMS INPUT calibration. “CHEC” will be displayed for 1
second. The new calibration constants are applied and the OHMS INPUT calibration
can be checked.
8. Push
to go to the next mode.
OHMS OUTPUT Low Range
1. In OHMS OUTPUT low range mode, the unit will display “ 15.00” and will source
OHMS using the default calibration.
2. Connect the 712 to the DMM in OHMS read using 4 wire mode connection (2 wires
at 712, 4 wires at DMM). The DMM should read 15.00 Ω ±5%.
3. Adjust the value for OHMS OUTPUT using the arrows on the 712 keypad to source
exactly 15.00 Ω.
4. Push
 to go to the next calibration point. “400.00” will be displayed
5. Adjust using the arrows on the keypad to source exactly 400.00 Ω.
6. Push
to complete OHMS OUTPUT low range calibration. “CHEC” will be
displayed for 1 second. The new calibration constants are applied and the calibration
can be checked.
7. Push
to go to the next mode.
OHMS OUTPUT High Range
1. In OHMS OUTPUT high range mode, the unit will display “ 20.0” and will source
OHMS using the default calibration. Keep the connections from the previous mode.
The DMM should read 20.0 Ω ±5%.
2. Adjust the value for OHMS OUTPUT using the arrows on the 712 keypad to source
exactly 20.0 Ω.
3. Push
to go to the next calibration point. “4000.0” will be displayed.
4. Adjust using the arrows on the keypad to source exactly 4000.0 Ω.
5. Push
 to complete OHMS OUTPUT high range calibration. “CHEC” will be
displayed for 1 second. The new calibration constants are applied and the calibration
can be checked.
6. Push
 to complete calibration.
