126 Operating Manual for Multichannel Functionality (GPIB-M)
Security code To protect calibration data, a security code is required to enter calibration mode. The
security code set at the factory to "0000." The password can be changed. Calibration
state must be ON to change the password.
The SCPI command to change the security code is:
CAL:CODE <security_code>
The security code is any 4-digit number enclosed by quotation marks. Trying to
change the password to an invalid one causes an error.
Setup and Equipment
To calibrate the option card you will need:
• 6 digit DVM
• current shunt
• variable load
• Load wiring sized for the maximum available output current.
To set up to calibrate output voltage and current:
Connect a load to the output of the power supply and a current shunt in series.
You will need to use the DVM to measure both the voltage at the output of the power
supply and the voltage across the shunt. You will need to convert the voltage across
the shunt to a current measurement.
