BATTERY OPERATION 
The meter may be operated on battery power, using a USB computer
adapter or USB computer connection. If using the meter as an in-store
water analysis lab, use the USB computer cable.
To charge the battery from a computer, plug the smaller end of the USB
cable (USB mini B connector) into the meter and the larger end of the USB
cable (USB Type A connector) into a USB port on the computer. Reinsert
the USB port plug after charging if using battery power.
To charge the battery with the USB wall adapter, plug the smaller end of
the USB cable (USB mini B connector) into the meter and the larger end of
the USB cable (USB Type A connector) into the wall adapter. Plug the wall
adapter into an AC outlet. Reinsert the USB port plug after charging if using
battery power.
The battery icon will show no bars and flash when the unit first turns on.
Then the indicator will indicate the battery status by showing 0, 1, 2, 3 or 4
bars.
It will take 5 hours to fully charge a low battery. The battery icon will flash
when the battery is charging. The battery icon will show four bars and stop
flashing when it is fully charged. The charging circuit will automatically
switch to a float charge when the battery is fully charged. The charger may
remain connected. Some computers will NOT supply power to their USB
ports during standby operation. The USB wall adapter will charge the unit
continuously.
The battery icon will show no bars and continuously flash if the battery is
getting low but the unit will still operate normally. A “Low Battery” message
on the status bar of the display will replace the time when the battery
voltage is too low for proper operation and accuracy may be degraded. A
“Shutdown Low Batt” message on the display will appear for a few seconds
before the power is switched off when the battery is too low to operate the
unit.
To extend the battery life:
Shut down the unit with the power switch when not taking •
measurements or use the power save option to have the unit
automatically turn off after 5 minutes.
Store the unit in a cool dry place.
•
Fully charge the battery before storing the unit for extended periods of •
time.
Limit backlight use. The unit consumes 3X normal power with the
•
backlight on.
Set the backlight time option to 10 seconds, or select “Button Control”
•
and keep the backlight off.
