OPERATION OF ACCESSORIES
3 - 3
NOTE 1: The latest version of the MultiRAE PLUS monitor
has a smart charging circuitry and algorithm to prevent
overcharging; removing the charger is not necessary.
NOTE 2: After one charging cycle the monitor recognizes
whether Li ion or NiCd batteries are installed. When NiCd
batteries are present, the firmware displays:
Deep
Discharge? when the AC adapter is connected. Perform
occasional deep discharge to the NiCd battery to maintain
full capacity by pressing the
[Y/+]
key when this message
appears. The battery will begin deep discharge followed by a
charge cycle. The deep discharge is useful to remove
memory effects of the NiCd battery, so that the charge
capacity is maintained.
The battery of the MultiRAE PLUS monitor will be drained
slowly even if the monitor is turned off. If the monitor has
not been charged for 5-7 days, the battery voltage will be
low.
The factory supplied battery is designed to last for 10 hours
of normal operation (no alarm, no back light condition) for a
new battery under the best condition. As the battery
becomes older or is subject to adverse conditions (such as
cold ambient temperature), the battery capacity may be
reduced significantly. Li ion batteries do not have a memory
effect and tend provide longer run time even at the same
mAh rating.
