Users Manual

Replacing the Batteries

The GMM test tool uses 6 AA alkaline batteries
(included with Model 863) or a nickel-cadmium
battery pack (BP 7217 - included with Model 867B).
Internal charging for the battery pack is provided with
Model 867B. The NiCd battery pack must be fully
charged before using the GMM. External charging
(using BC7210) is necessary if the battery pack is
used with Model 863 (instructions are included with
BC7210.) Refer to Figure 7-2 for battery replacement
instructions. Replace the NiCd battery pack when it
no longer holds a charge for the rated interval. Order
replacement Model BP7217 Nickel-Cadmium Battery
Pack. In the USA and Canada, call Fluke Service
Parts at (800) 526-4731. Elsewhere, call +1 425-
356-5500 for instructions.

Note
If the Tester is dropped, it may not turn on.
Check the batteries to see if they are
damaged and need to be replaced.
Do not mix spent Nickel-Cadmium batteries with the
solid waste stream. Spent batteries should be
7-2
disposed of by a qualified recycler or hazardous
materials handler. Contact your authorized Fluke
Service Center for recycling information.

Replacing the 440 mA Fuses

m
Warning
Refer to SAFETY in the front of this
manual prior to replacing any fuse.
Refer to Figure 7-3 to locate and replace the 440
mA fuse(PN 934121). Note that the battery
compartment must be accessed first; refer to Figure
7-2 for these initial access procedures.
Replacing the 11A (High Energy)
Fuse
You must disassemble the GMM case to replace a
blown high energy (1000V, 11A) fuse (PN 943118).
The GMM's safety design places this fuse inside the
case to protect the user and to encourage inspection
of the circuit board for damage if very high energies
have been encountered. Proceed as follows:
1. Set the GMM selector to OFF. Be sure to leave
the selector in this position throughout the
disassembly and reassembly procedure.
