If the Meter Does Not Turn On
Use the following steps to help solve problems you might experience
when turning on the meter. If you need more help, see the
Service Guide
for instructions on returning the meter to Hewlett-Packard for service.
1 Verify there is ac power to the meter.
First verify that the meter’s power switch is in the "On" position. Make
sure the power cord is firmly plugged into the power module on the
meter’s rear panel. Verify that the power source is energized.
2 Verify the power-line voltage setting.
The line voltage is set to the proper value for your country when the
meter 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 diagram on the next page to verify or change the setting.
To replace the 250 mAT 250 V fuse, order part number 2110-0817.
This fuse is used for all power line voltage settings.
