3.1 Battery Usage
3.2 Battery Charge
1.5V x 2 (Mignon / AA / IEC R6 or equivalent, 2000-2400mAh
Use rechargeable batteries only. NEVER use normal alkaline
batteries!
A T T E N T I O N !
NEVER try to charge normal alkaline batteries as there is
the risk of explosion!
Place the batteries into the compartment in the rear bottom part
of the data logger. Make sure that the polarity of the batteries (+/-)
coincides with the respective marks on the bottom of the com-
partment. The data logger is ready after a period of 10 seconds
and the square LED will begin flashing. Wrong insertion of bat-
teries causes a failure of the functionality of the data logger and
batteries will be totally discharged after about one hour, but the
data logger will not be damaged.
To charge the batteries, plug the cord of the AC power adaptor
to the power connector of the data logger. The data logger will
switch off automatically. The normal charging period is 3.5 hours.
The electronic charging system ensures that the batteries are
always completely charged and never will be over-charged. Use
the supplied power adaptor only, otherwise the internal electro-
nics may be damaged!
The charging process is indicated by flashing of the square-LED
on the front of the data logger. The LED will extinguish if charging
is completed.
Very deeply discharged batteries cannot be recognized by the
electronic charging system and thus will not be charged. Please
remove such batteries and charge them with a suitable battery
charger.
IMPORTANT NOTE:
The
effective
capacity of the utilized batteries is critical for the
operating span of the data logger. The effective capacity of
rechargeable batteries decreases inevitably over time, even with
constantly thourough handling. Rechargeable batteries with an
indicated capacity of 2000mAH, for example, will have an effec-
tive capacity of only about 1500mAH after permanent usage
for two years. So, regardless of the quality of maintenance, the
effective capacity is just about 75% of the original value. With
insufficient care the effective capacity can even go far below 50%
of the indicated capacity. Correspondingly, the operating span
of the MOUSE-E-MOTION Universal Data Logger is significantly
reduced when such batteries are used.
