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.
SECURED
Turn on the calibration mode by pressing the Calibrate key
while simultaneously turning on the power supply then
continue to hold the Calibrate key for about 5 seconds
until a beep is heard.
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 the Secure key.
000000 CODE
3 Enter the security code using the knob and resolution
selection keys.
003632 CODE
The security code is set to “HP003632” 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.
