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.

You can select either 4½ or 5½ digit
resolution for most measurement functions.
5½ digit readings have the best accuracy and
noise rejection. 4½ digit readings provide for
faster readings.
