Examine the meter carefully, familiarizing yourself with the
layout of the input terminals, rotary switch, pushbuttons
and display. Notice the Warning information and summary
of power-on options engraved into the rear panel.
If you have used a multimeter before, simply examining
your meter will probably give you a good idea how to use
it. The following procedure is an overview of how to take
basic measurements.
To avoid electrical shock or damage to the
meter, do not apply more than 1000V between
any terminal and earth ground.
1. Insert the test leads in the appropriate input terminals
(see Table 2). If the test leads are in the wrong input
terminals when the meter is turned on and the beeper
has not been disabled, the beeper will emit a
warning. See "Input Terminals and Input Alert",
