Step 5 
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 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. 
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.
