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 Chapter 5 for instructions on returning the
instrument to Agilent 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.
