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

1.Reset the unit.

2.Enable calibration mode. (0 is the default password)

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).

4.Save the password.

5.Exit Calibration mode. (*RST also exits calibration mode)

Program Commands

“*RST”

“CAL:STAT ON, 0” “CAL:PASS <password>”

“CAL:SAVE” “CAL:STAT OFF”
