Remote Voltage Calibration - Tektronix Keithley 2281 Series Reference Manual

Model 2281S-20-6 DC Power Supply and Battery Simulator Reference Manual

Remote voltage calibration

Connect the instrument to a digital multimeter (DMM). For details, see
(on page C-7).
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
For the 2281S, the expected values are shown in the following table.
Steps

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.
Step 2
1. Prepare for step 2 by sending the command:
:CALibration:PROTected:STEP2
2. Send the measured result from the digital multimeter (DMM) by sending the command:
:CALibration:PROTected:STEP2:DATA <voltage>
3. Send the following command to query the operation status:
*OPC?
After all of the operations are completed, the instrument returns 1.
