Step 7
1. Before calibration, configure the shunt and load (electronic load or resistor load), as shown in the
following table.
Model
Shunt
Electronic load
Resistor load
2281S
0.05 Ω
Constant current mode
32 V
6.0 A
5 Ω
2. Send the command to prepare for step 7:
:CALibration:PROTected:STEP7
3. Send the measured result from the digital multimeter (DMM) and shunt value by sending the
command:
:CALibration:PROTected:STEP7:DATA <voltage>, <resistance>
4. Send the following command to query the operation status:
*OPC?
After all of the operations are completed, the instrument returns
1
.
Step 8
1. Before calibration, configure the shunt and load (electronic load or resistor load), as shown in the
following table.
Model
Shunt
Electronic load
Resistor load
2281S
0.05 Ω
Constant voltage mode
30 V
6.5 A
5 Ω
2. Send the command to prepare for step 8:
:CALibration:PROTected:STEP8
3. Send the following command to take internal measurements and calculations:
:CALibration:PROTected:STEP8:DATA
4. Send the following command to query the operation status:
*OPC?
After all of the operations are completed, the instrument returns
1
.
Remote low-sink current calibration
Perform the following steps to finish the low-sink current calibration:
Step 9 and step 10: Sink-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.
