Changing the Calibration Password
The factory default password is 0. You can change the password when the dc source is in calibration
mode (which requires you to enter the existing password). Proceed as follows:
Action Program Commands
1. Reset the unit. “*RST”
2. Enable calibration mode. (0 is the default password) “CAL:STAT ON, 0”
3. Enter the new password. You can use any number with up to six
digits and an optional decimal point. If you want the calibration
function to operate without requiring any password, change the
password to 0 (zero).
“CAL:PASS <password>”
4. Save the password. “CAL:SAVE”
5. Exit Calibration mode. (*RST also exits calibration mode) “CAL:STAT OFF”
