Step 5
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
0.05 Ω
Constant current mode
1.5 V
0.06 A
5 Ω
2280S-60-3
0.05 Ω
Constant current mode
1.5 V
0.03 A
20 Ω
2. Send the command to prepare for step 5:
:CALibration:PROTected:STEP5
3. Send the measured result from the digital multimeter (DMM) and shunt value by sending the
command:
:CALibration:PROTected:STEP5:DATA <voltage>, <resistance>
4. 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 6
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
0.05 Ω
Constant voltage mode
0.3 V
0.5 A
5 Ω
2280S-60-3
0.05 Ω
Constant voltage mode
0.6 V
0.5 A
20 Ω
2. Send the command to prepare for step 6:
:CALibration:PROTected:STEP6
3. Send the following command to take internal measurements and calculations:
:CALibration:PROTected:STEP6:DATA
4. Send the following command to query the operation status:
*OPC?
After all of the operations are completed, the instrument returns 1.
