Replacement Batteries
This manual does not list all possible
accessories that AMPTEC RESEARCH is
willing to provide as a support items for the
640N Igniter Tester. Contact the sales
department at AMPTEC if you have a request
for an item that is not described here. Listed
below are the options available for use with the
AMPTEC 640N Igniter Tester.
Option "640DC" is an AC/DC converter that
converts 115VAC line voltage to 9VDC at 1.1A.
The 640 Battery Charger is fitted with the
mating plug that connects to the unit’s J1
connector. One charger is provided as a standard
accessory with every 640N Ohmmeter.
The rechargeable NICAD batteries installed in
the 640N should provide trouble-free operation.
Replacement, however, will eventually be
necessary. The 640N uses four 1.2V cells (5.7
AHr recommended) installed in a reusable
battery box. The batteries are held in place by a
metal retaining plate. When ordering
replacement batteries, please specify AMPTEC
Stock #05-10117, quantity four (4).
Replacement AMPTEC 640N NICAD batteries
come with an inspection sticker that verifies
each individual replacement battery voltage
(charge level), inspector signature, along with
the inspection date.
