Powering the Tester
The Tester uses a 9-volt alkaline battery. It uses as much
of the battery as possible. When it detects less than about
6.8 V, it sounds a continuous tone alarm. When it detects
less than 6.0 V, it goes into a shutdown mode
The battery resides in the base of the instrument. Use a
9-volt alkaline battery (Duracell
®
MN1604 or equivalent).
Do not use a mercury, air, or carbon-zinc battery.
W Warning
The 9-volt alkaline battery provided with the
Tester may explode or leak if recharged,
inserted improperly, disposed of in a fire, or
mixed with different battery types. Dispose of
the battery in accordance with any applicable
state or local regulations.
As an alternative to a battery, you can power the Tester
with a Fluke Biomedical Battery Eliminator. To ensure
safe operation, use only a Fluke Biomedical Battery
Eliminator (PN 2647372).
WXWarning

Battery Eliminator specified in this manual or
