Battery Status and Charging
The battery level icon appears in the upper right-hand corner of the screen. A fully charged battery will have 5
bars showing. As the battery level drops during use, the number of bars will decrease from right to left. NiMH
batteries constantly work at regenerating themselves and releasing more power. It is possible for the displayed
battery level to fluctuate (increase or decrease) during use.
When the battery level becomes very low (1 bar), the red LED will start flashing. Some additional samples may
still be taken, but the unit should be plugged into power source using the AC adapter as soon as possible. The
pump may be operated using standard AC power supplied by the charger.
If the battery’s voltage drops low enough that the unit will not operate reliably or if for any reason an
inconsistent motor speed is detected, the unit will shut down. During shutdown, the amount of actual run time
will be saved. When the power is restored,
Incomplete Run
will be displayed on the home screen. Previous
sample may be continued, or a new sample may be started.
To charge the battery pack, plug in the AC charger on the right side of the pump. The yellow LED will flash when
the unit is charging. When charging is complete, the yellow LED will remain constant. A full battery charge takes
approximately 3 hours. If the pump will not be used for an extended period, it will slowly lose its battery charge
and will need to be recharged before use. During these extended periods, the pump can be kept on AC power so
the battery receives a trickle charge. The pump can perform all sampling modes while charging. If charging and
sampling or calibrating at the same time, the LED will alternate between flashing yellow and green.
