To Change the Security Code
To change the security code, you must
first unsecure the power supply, and then enter a new code.
Be sure to read the security code rules on page 58 before attempting to
secure the power supply.
• Front-Panel Operation:
To change the security code, first make sure that the power supply is
unsecured
. Press the key after the “CAL MODE” message is
displayed in the calibration mode, enter the new security code using the
knob and resolution selection keys, then press the
key.
Changing the code from the front panel also changes the code required
from the remote interface.
• Remote Interface Operation:
CALibrate:SECure:CODE

security code. Then, enter the new code. For example,

"CAL:SEC:CODE ZZ001443"

"CAL:SEC:STAT ON, ZZ00143"
