Getting Started
2) Battery Status Indicator
The battery status indicator on the pump LCD screen shows the current battery charge level:
Fully charged. Three bars displayed from approximately 100% to 75% capacity. Note: It is
strongly recommended to ensure that the battery is fully charged before starting a sample
run.
Two bars displayed from approximately 75% to 25% capacity.
One bar displayed below approximately 25% capacity.
Low battery. No bars and flashing outline indicates low battery. Pump automatically switches
to HOLD mode, and then SLEEP mode within 10 seconds.
Note: When the pump stops due to a low battery and is left to stand for a period of time,
one bar may appear on the battery status indicator when the LCD screen is activated. This
false “recovery” will fall quickly if the pump is operated without recharging it. RECHARGE
THE PUMP BEFORE SAMPLING.
3) SLEEP Mode
If the pump is left in HOLD mode for longer than five minutes the pump will automatically set itself to a low
power SLEEP mode, with the LCD screen switched off. To wake the pump from SLEEP mode simply press any
of the three buttons and the pump LCD screen will activate and display the last four digits of the pump serial
number followed by the internal software version number before switching to HOLD mode.
