Step 3
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
2280S-32-6
5.05 Ω
Constant current mode
1.5 V
0.001 A
300 Ω
2280S-60-3
5.05 Ω
Constant current mode
1.5 V
0.001 A
300 Ω
2. Send the command to prepare for step 3:
:CALibration:PROTected:STEP3
3. Send the measured result from the digital multimeter (DMM) and shunt value using the following
command:
:CALibration:PROTected:STEP3: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 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 1.
