RKI Instruments Eagle Series - Manual (Page 57)

52 • Maintenance Diffusion Eagle Instruction Manual
Eagle battery charger can determine if alkaline batteries are
installed and will stop charging them automatically. Using any
other battery charger can result in alkaline battery leakage or
explosion if alkaline batteries are accidentally charged.
NOTE: Setup mode allows you to select between alkaline and Ni-Cd
batteries. The two types of batteries have unique low battery alarm
characteristics. To prevent unexpected low battery alarms, always
make sure the battery type setting in Setup mode matches the type of
batteries installed in the Eagle.
Replacing Ni-Cd Batteries
NOTE: Ni-Cd batteries should only be replaced when they no longer
hold a charge.
1. Turn off the Eagle.
2. Unscrew the two large screws on the top of the case, then carefully lift the
top of the case and lay it aside.
3. Remove the batteries and verify that the battery compartment and
electrical contacts are clean.
4. Insert fresh batteries following the label on the inside of the case.
5. Place the top of the case in its original position, then secure it with the
large screws you loosened in step 1.
Replacing Sensors
Electrochemical sensors (O
2
, H
2
S, and CO) gradually deteriorate, regardless
of use, and require periodic replacement. Combustibles sensor life is
typically related to usage, but certain conditions may affect duration.
The Eagle sensors are easy to replace but do not contain user-serviceable
components. For genuine RKI sensors, call RKI or your local distributor. All
sensors are covered by a limited warranty; see warranty for details.
CAUTION: Avoid pulling on sensor wires. Always unplug at the
connector.
