Step 4
1. Before calibration, configure the shunt and load (electronic load or resistor load), as shown in the
following table.

2. Send the command to prepare for step 4:
:CALibration:PROTected:STEP4
3. Send the measure result from the DMM and shunt value using the following command:
:CALibration:PROTected:STEP4:DATA <voltage>, <resistance>
4. Send the following command to query the operation status:
*OPC?
After all of the operations are completed, the instrument returns

.
Remote high-current calibration
Connect the instrument with the digital multimeter (DMM), precision shunt resistor, and electronic load
(or resistor). For details, see
Current calibration connections
(on page C-8).
Perform the following steps to finish the remote high-current calibration:
Steps 5 through 8: Current calibration on the 1 A and 10 A
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.
You can send
SYST:ERR?
to query any error messages and error event codes. For calibration error
messages and codes, refer to
(on page 8-3).
For the 2281S, the expected values are shown in the following table.
