Power Supply
2-4.
The GMM can be powered with a Fluke BP7217 rechargeable battery pack (6 - 4/3A
NiCd cells), 6 AA alkaline batteries, or a battery eliminator. The GMM automatically
detects power by source (NiCd battery pack, AA alkaline batteries, or battery
eliminator.) Diodes provide reverse polarity protection for the batteries.
The NiCd battery pack recharges in a minimum of 16 hours when the GMM is not
operating or at a trickle rate while the GMM is operating. Only cells in the Fluke BP7217
battery pack can be charged internally. Internal charging is not available with Model 863.
Caution
Do not attempt to place other batteries in the BP7217 battery
pack; damage to the batteries could result.
A low battery indicator ( ) comes on when battery voltage drops below a preset
voltage level. This level is the same for all types of batteries: remaining battery life can
vary from minutes to hours, depending on battery type, ambient temperature, and battery
history. A low-battery power down can also occur. (No automatic power down occurs
when the GMM is powered by the battery eliminator.)
Refer to Chapter 1 for battery and battery eliminator specifications.
