Calibration and Troubleshooting

B-26

M370046-01

By saving and reloading the calibration parameters using these 
commands, you can calibrate the XTR for maximum accuracy for a 
specific load and then switch loads and load a calibration set that is 
accurate at maximum accuracy for the new load.

Restore Factory Calibration

To restore factory calibration, use the SCPI command for returning the 
power supply to factory calibration settings.

The SCPI Command (s) for these instructions are: 

[:]CALibration:RESTore

Important: 

Factory calibration is not the same as the shipped calibration. 

Using this command will likely necessitate recalibrating all controls.
