Step 2
1. Enter the measured result from the DMM.
2. After entering the data, the waiting window is displayed. You need to wait a few seconds for the
internal measurements and calculations. Then the Save window is displayed.
3. You can save the calibration results or continue to the next calibration step. For the details on
saving, see
Saving calibration constants from the front panel
(on page C-19). If you want to
continue the calibration, press the
Next
soft key.
After each calibration step, the 2281S output is set to a safe low-voltage level, preventing inadvertent
harm to the user, instrument, or load.
Low-current calibration
Perform the following steps to finish the low-current calibration:
Step 3 and step 4: Current calibration on the 10 mA and 100 mA ranges
You must input the measured value from the DMM. The value should be within the expected range.
A message will indicate if the DMM data entry was out of the expected range. Verify that the proper
shunt value was used or that the cables are properly connected.
