Zero Offset Verification
This procedure checks the instrument’s zero offset performance. Verification checks are only performed
for those functions and ranges with unique offset calibration constants. Measurements are checked for
each function and range as described below.
1.
Make sure you have read Test Considerations.
2.
Install the 34172B Calibration Short (or equivalent) on the front panel input terminals. Select the
Front input terminals with the Front/Rear switch.
3.
Configure each function and range in the order shown in the table below corresponding to the DMM
model number. Make a measurement and return the result. Compare measurement results to the test
limits shown below.
4.
Install the 34172B Calibration Short (or equivalent) on the rear-panel input terminals. Select the Rear
input terminals with the Front/Rear switch.
5.
Configure each function and range in the order shown in the table below corresponding to the DMM
model number. Make a measurement and return the result. Compare measurement results to the test
limits shown below.
