Remote voltage calibration
1. Connect the digital multimeter (DMM) to the instrument. For details, see Voltage calibration
connection (on page C-7).
2. Perform calibration step 1 and step 2.
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.
You can send SYST:ERR? to query any error messages and error event codes. For calibration error
messages and codes, refer to Error summary (on page 8-3).
For the Model 2280S-32-6, the expected value is shown in the following table.
For Model 2280S-60-3, the expected value is shown in the following table.
Step 1
1. Send the following command to prepare calibration step 1:
CALibration:PROTected:STEP1
2. Send the measured result from the digital multimeter (DMM) by the command:
CALibration:PROTected:STEP1:DATA <voltage>
3. The instrument begins to take internal measurements. This will take a few seconds. To query the
operation status, send the command:
*OPC?
After all of the operations are completed, the instrument returns 1.
