If the Instrument 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 the
34970A Service Guide for instructions on returning the instrument to
Agilent for service.
1 Verify that there is ac power to the instrument.
First, verify that the power cord is firmly plugged into the power
receptacle on the rear panel of the instrument. You should also make
sure that the power source you plugged the instrument into is
energized. Then, verify that the instrument is turned on.
The On/Standby switch is located on the lower left side of the front panel.
2 Verify the power-line voltage setting.
The line voltage is set to the proper value for your country when the
instrument is shipped from the factory. Change the voltage setting if
it is not correct. The settings are: 100, 120, 220, or 240 Vac.
Note: For 127 Vac operation, use the 120 Vac setting.
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 instrument is shipped from the factory with a 500 mA fuse installed.
This is the correct fuse for all line voltages.
See the next page if you need to replace the power-line fuse.
To replace the 500 mAT, 250 V fuse, order Agilent part number 2110-0458.
