Battery Operation - Universal Flow Monitors FlowStream FD Series User Manual

BATTERY OPERATION

The flowmeter includes an internal 800 mAh Lithium-Polymer battery that allows for 40 hours
of continuous operation. The battery can be charged from any USB charger, and it typically
takes 2 hours for a full charge when using a 1-Amp charger. When the meter is plugged into a
PC for data logging, the battery will continue to charge through the USB port. A full charge
through the computer USB port will take longer than 2 hours, as PC USB ports are limited to
500 mA of output current.
The charge LED on the unit (CHG) indicates the battery status while plugged into a charger.
Yellow means battery is charging.
Green means battery is fully charged.
Note: If the meter is plugged into an external charger or a PC, the battery continues to charge
while the meter is operating.
