Powering the Tester
You can power the tester with four AA alkaline batteries
(included), four rechargeable nickel-metal hydride or
nickel-cadmium batteries, or four 1.5 V lithium batteries.
Most of the tester’s screens show a battery status icon
(b) near the upper-left corner. The message Low
Batteries! appears when the batteries are too low for the
tester to function.
The batteries last about 20 hours during typical use (with
the backlight at the dim setting).
Figure 26 on page 65 shows how to replace the batteries.
Verifying Operation
The tester performs a basic self-test when you turn it on. If
the tester reports an error or does not turn on, refer to “If
Something Seems Wrong” on page 65.
