To Unsecure the Power Supply for Calibration
The power supply can use a calibration security code to prevent unauthorized
or accidental calibration. This procedure shows you how to unsecure the
power supply for calibration from the front panel.
1 Turn on the front-panel calibration mode.
Turn on the calibration mode by holding down (Calibrate) key as you
turn on the power supply and hold down the key until you hear a long beep.
If the power supply is secured, you will see the above message from the front
panel for approximately one second. The ‘‘CAL MODE’’ message is then
displayed on the front panel.
2 Move to the security code by pressing (Secure) key.
3 Enter the security code using the knob and resolution selection keys.
The security code is set to ‘‘HP003633’’* or ‘‘HP003634’’** when the power
supply is shipped from the factory. The security code is stored in non-volatile
memory and does not change when the power has been off or after a remote
interface reset.
• To enter the security code from the front panel, enter only the last six
digits.
• To enter the security code from the remote interface, you may enter up to
12 characters.
Use the resolution selection keys to move left or right between digits. Use the
knob to change the digits. Notice that the security code may be different if the
security code has been changed from the default setting.
