Turn On The Multimeter - Agilent Technologies 34405A Guide De Démarrage Rapide

4. Turn On the Multimeter

Press the Power (on/off) switch:
The front-panel display illuminates while the
multimeter performs its power-on self-test.
Following self-test, the multimeter defaults to
DC voltage measurements.* Typical display:
Measurements are shown in the primary
display (bottom left) and the measurement
range is shown in the secondary display (top
right).
*You can set the multimeter to return to the last
power-down state when power is applied. See the
34405A User's and Service Guide for details.
6. Set the Range
For most measurement functions, you can let
the multimeter automatically select the range
using autorange or you can select a fixed
range using manual ranging. The ManRng
