MIL-PRF-83323C
3.6.20 Rechargeable Batteries. The batteries shall be of the rechargeable sealed nickel-cadmium type and shall
provide nominal 28V to the tester power monitor (see figure 2). The batteries shall be capable of 1-hour
continuous operation from a fully charged condition between -18C and 52C (0and 125F). Reduced operating
time of at least 15 minutes is acceptable between -40 C to -18C (-40F to 0F) and 52C to 66C (125F to
150F). A positive method of connecting the batteries to the tester shall be provided.
3.6.21 Battery Charger/Power Monitor. A charger capable of restoring the batteries to full charge in 4 hours
after 1 hour s operation shall be included in the unit. The charger shall operate from 115V AC, 60 Hz. The
charge light shall illuminate whenever charging is occurring. A power monitoring circuit shall be included to
prevent short circuit or deep discharge of the batteries. This circuit shall shut off power to the electrical box when
the terminal voltage of the battery drops too low for continued operation.
3.6.22 Headset Amplifier. A headset amplifier or equivalent with volume control shall be provided within the
electrical box and electrically installed as shown on figure 2. If required, the wiring shall be shielded between pins
of the signal amplifier and the headset amplifier. The signal amplifier shall be a Data Products New England, Inc.
P/N 2119 or equivalent. The volume control knob shall be labeled VOLUME and the potentiometer shall be per
MIL-PRF-94/3 or equivalent.
3.6.23 Container. The container shall be constructed of a material suitable for permanently housing the tester.
The tester shall be positively held in place within the container when the container is held or placed in any
position. The container shall meet the requirements of paragraph 4.4.13,, and this specification. The case shall be
constructed of aluminum, plastic or a combination resin bonded material. All corners shall be rounded with at
least ¼ radius. The cases shall be provided with quick-opening spring loaded or pull-down tension type latches.
The main portion of the latch shall be on the case body and the smaller portion of the case cover. The latch shall
be protected from damage by contact with other objects. Figure 1 shall be used for sizing the container. An
electrical power cord shall be contained within the container. The cord shall be a minimum of 6 feet long. On one
end, a standard 60 Hz, 115V AC plug shall be provided. The other end shall mate with the electrical box s charge
connector. Charging shall be accomplished by plugging the electrical test box when the switch marked POWER is
in the OFF/Recharge position. Recharging shall only take place between4 C and 38 C (40F and 100F).
3.6.24 Grounding Cable. A grounding cable in accordance with MIL-DTL-83413/7 and MIL-DTL-83413/10 (except
that no ferrous materials shall be used), with grounding plugs on each end shall be provided. A minimum length of 10
feet shall be required.
3.6.25 Adjustable Restraining Device. A restraining device shall be provided for securing the tester to those
receptacles capable of accepting it. The restraining device shall insert the nozzle into the receptacle when the
tester s handles are actuated; and shall prevent the forcible ejection of the tester from the receptacle in case of
inadvertent disconnect while under fuel pressure. The restoring device shall be infinitely adjustable from a
minimum distance of 6 inches to a maximum distance of 3 feet. It shall be designed to interfere with those
receptacles incorporating attachment points, in accordance with or equivalent to, those defined on XAR Dwg-
7034. The restraining device shall be capable of withstanding the structural test of 4.4.11.5.
3.6.26 Pedestal/Sliding Valve Assembly Removal Tool. A removal tool shall be provided for removing the
pedestal/sliding valve assembly for those receptacles having the capability of removing these parts from the front of
the receptacle.
3.6.27 Headset Adapter Cable. A cable shall be provided to adapt the H-157/AIC headset to the tester electrical
box. The adapter cable shall be equipped with a push-to-talk switch and the other end terminating in an electrical
connector plug in accordance with SAE-AS31061 (SAE part number MS3106A16S-1P).
