. Always be certain
that the batteries are correctly
positioned in the battery holder.
Then carefully replace the

2. The UltraTester 3+ batteries may
be charged by placing it in the
optional UltraDock 3 battery
charging station with the micro-
USB power cord plugged into the
rear of the charging station or by
plugging its supplied micro-USB
power cord into the rear of the
tester and the USB adapter cube
directly into a wall outlet. Once
the tester is connected to the AC
adapter or the charging station,
the tester will switch to its DC
power mode. The tester’s built-in
Intelligent Charging Circuit “ICC”
will automatically identify the
type of batteries installed (NiMH
rechargeable batteries or alkaline
batteries). If alkaline batteries
are installed, the circuit will
automatically cut off the power
supply to the batteries so that
the alkaline batteries will not be
recharged. If NiMH rechargeable
batteries are installed, the
batteries will be recharged and
at the same time the tester may
be used with the AC adapter.
3. To turn the UltraTester 3+ ON
press the oval shaped power
button, located on the top center
edge of the tester

warm-up time is approximately
25 seconds. When it has fully
warmed up, the flashing green
LED light will become solid and
a beep tone will be sounded. You
may now begin using the tester.
