Battery Information
Charging a New Battery
The NiMH battery supplied with the Cell Master has already completed charge and dis-
charge cycles at the factory and full battery performance should be realized after your first
charge.
NOTE: The battery will not charge if the battery temperature is above 45 ° C or
below 0 ° C.
Charging the Battery in the Cell Master
The battery can be charged while installed in the Cell Master.
Step 1. Turn the Cell Master off.
Step 2. Connect the AC-DC adapter (Anritsu part number: 40-168) to the Cell Master
charging port.
Step 3. Connect the AC adapter to a 120 VAC or 240 VAC power source as appropriate
for your application.
The green external power indicator on the Cell Master will illuminate, indicating
the presence of external DC power, the battery charge indicator will light, and
the battery will begin fast charging. The charging indicator will remain lit as
long as the battery is fast charging. Once the battery is fully charged, the fast
charging indicator will turn off and a trickle charge will be started to maintain
battery capacity. If the battery fails to charge, contact your nearest Anritsu ser-
vice center.
NOTES: If a battery is excessively discharged, it may require several hours of
trickle charging before the charger will allow a fast charge. Switching to fast
charge mode is not automatic. You must either cycle the power on and off, or
disconnect and reconnect the AC-DC adapter.
If the battery temperature exceeds 45 ° C while charging, the charging will stop
and the charge indicator will turn off. Charging will resume automatically when
the temperature drops below 45 ° C.
Charging the Battery in the Optional Charger
Up to two batteries can be charged sequentially in the optional battery charger.
Step 1. Remove the NiMH battery from your Cell Master and place it in the optional
charger (Anritsu part number 2000-1029).
Step 2. Connect the lead from the AC-DC adapter to the charger.
Step 3. Connect the AC-DC adapter to a 120 VAC or 240 VAC power source as appro-
priate for your application.
