Buzzer
A solid-state electronic buzzer is located on the front of the top case. It is a
panel mounting type of buzzer and is water resistant and sealed to the inside
of the top case with an O-ring. The buzzer sounds for gas alarms,
malfunctions, low battery voltage, and as an indicator during use of the
EAGLE 2’s many display and adjustment options.
Battery Case & Batteries
Four C-size alkaline batteries (standard) or optional rechargeable
C-size Ni-MH batteries power the EAGLE 2. They are installed in the battery
case which is located at the rear of the bottom case. The battery case is
secured to the bottom case with a thumbscrew.
Instrument run time is dependent upon battery type. At 25°C, alkaline
batteries power the EAGLE 2 for 16 hours of non-alarm operation.
Ni-MH batteries will power the EAGLE 2 for 18 hours of non-alarm
operation. The current battery voltage is viewable in Display Mode (see
“Display Mode” on page 40).
When the EAGLE 2 detects low battery voltage, a low battery warning is
activated. When battery voltage is too low for operation, the EAGLE 2
sounds a dead battery alarm.
The alkaline or Ni-MH batteries can be accessed for replacement by
unscrewing the thumbscrew that secures the battery case to the bottom case
and pulling the battery case away from the bottom case. The Ni-MH batteries
can be recharged by using the EAGLE 2 charger (see “Replacing or
Recharging the Batteries” on page 72).
NOTE: Use of batteries or battery chargers not specified by RKI
Instruments, Inc. will void the CSA classification and may void the
warranty.
