3 Connect the power cord and turn on the instrument.
The front-panel display will light up briefly while the instrument performs its
power-on self-test. The instrument initially powers up with all measurement
channels turned off. To review the power-on display with all annunciators
turned on, hold down
as you turn on the instrument. Note that a battery
must be installed in the unit in order for it to boot up. The battery is installed
when you receive the unit from the factory; this is only a consideration if you
remove the battery for some reason. If the instrument does not turn on
properly, see page 49.
4 Perform a complete self-test.
The complete self-test performs a more extensive set of tests than those
performed at power-on. Hold down as you turn on the instrument and
hold down the key until you hear a long beep. The self-test will begin when
you release the key following the beep.
If the self-test fails, see the 34970A/34972A Service Guide for instructions on
returning the instrument to Keysight for service.
