Installing Batteries

The APM 150 uses three (3) AA size non-
rechargeable batteries. The unit is shipped with
batteries not installed. You will find the batteries
in the instrument package.
Figure 1—Front view
To install the batteries:
! Loosen the battery cover screw on the front of
the instrument.
! Slide the cover left and lift it out (Fig. 1).
! Install the batteries over the pull strap, taking
care to observe each battery's polarity.
! Replace the cover and tighten the screw.
Note: When the batteries become low, the LCD
will show [ ] above the reading. From
that point, you will have about one hour of normal
use left. If [ ] comes on continuously and
replaces the reading, the battery voltage is too low
for accurate measurements and the meter will turn
itself off.
Always keep a replacement set of new batteries
available.

Preparing the Instrument

The meter is shipped with its auto shut-off feature
enabled. This setting will automatically turn the
unit off after a twenty-minute period of keypad
inactivity. To disable this feature, follow the
instructions in the menu selections (see page 11).
Before removing any parts from the carrying case,
the arrangement of the various items should be
noted so that repacking can be done easily. See
Figures 2 and 3.
