If the function generator does not turn on
Use the following steps to help solve problems you might experience
when turning on the function generator. If you need more help, see the
Service Guide for instructions on returning the function generator to
Hewlett-Packard for service.
1 Verify that there is ac power to the function generator.
First, verify that the function generator’s Power switch is in the
“On” position. Also, make sure that the power cord is firmly plugged into
to the power module on the rear panel. You should also make sure that
the power source you plugged the function generator into is energized.
2 Verify the power-line voltage setting.
The line voltage is set to the proper value for your country when the
function generator is shipped from the factory. Change the voltage
setting if it is not correct. The settings are: 100, 120, 220, or 240 Vac
(for 230 Vac operation, use the 220 Vac setting).
See the next page if you need to change the line-voltage setting.
3 Verify that the power-line fuse is good.
The function generator is shipped from the factory with a 500 mAT fuse
installed. This is the correct fuse for all line voltages.
See the next page if you need to change the power-line fuse.
To replace the 500 mAT fuse, order HP part number 2110-0458.
