If the Power Supply Does Not Turn On
Use the following steps to help solve problems you might encounter when turning
on the instrument. If you need more help, refer to
for instructions on
returning the instrument to Keysight Technologies for service.
1 Verify that there is AC power to the power supply.
First, verify that the power cord is firmly plugged into the power receptacle on
the rear panel of the power supply. You should also make sure that the power
source you plugged the power supply into is energized. Then, verify that the
power supply is turned on.
2 Verify the power-line voltage setting.
The line voltage is set to the proper value for your country when the power
supply is shipped from the factory. Change the voltage setting if it’s not
correct. The settings are: 100, 115, or 230 Vac.
3 Verify that the correct power-line fuse is installed.
The correct fuse is installed for your country when the power supply is shipped
from the factory. See the table below to replace the fuse for your power supply.
