10. The unit is powered by a rechargeable NiMH battery pack.
The unit will also work with the “AA” battery pack. Six
“AA” batteries are required. Dispose of the batteries per
your company procedures. See Care & Maintenance for
more information on using the rechargeable battery pack.

Voltage Termination
1. The Voltage Termination
option allows you to select
the input impedance of the
965AMS digital voltmeter
(in supported countries
only). The input impedance
of the internal 965AMS
voltmeter is normally
1Mohm. However, some
legacy systems use voltage
measurement systems
with input impedances of
100Kohms. This option
is provided to maintain
measurement compatibility
with those systems.
If 100Kohm termination is
selected, the 965AMS tester
will display ‘100K’ on the
voltage measurement.
