 BATTERY/AC OPERATION
The SMART3 may be operated on battery power, using a USB wall adapter or
USB computer connection. If using the meter as a bench top unit, use the wall
adapter if possible to extend the battery life. The meter will remain on when the
USB adapter is used.
To charge the battery with the 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.
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 a computer.
The battery icon will show no bars and fl ash when the unit fi rst 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 fl ash when
the battery is charging. The battery icon will show four bars and stop fl ashing
when it is fully charged. The charging circuit will automatically switch to a fl oat
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 wall adapter will charge the unit continuously.
The battery icon will show no bars and continuously fl ash 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.
Battery replacement: The lithium ion battery used in this unit should last for
many years with normal use. When it no longer powers the unit long enough to
meet testing requirements it will need to be replaced. Lithium ion batteries that
are properly charged and stored do not usually lose all capacity; they just have
