BATTERY/AC OPERATION

The 2020t/i may be operated on battery power or using the 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 lithium ion 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. Reinsert the USB port plug after charging.
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
the 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 three times the 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 less capacity after hundreds
of charge cycles. This unit uses a custom battery assembly that is only available from
LaMotte Company. Battery replacement must be performed at a LaMotte authorized
repair facility. The water resistant housing of this meter should not be opened by the user.
Contact LaMotte Company by phone (1-800-344-3100) or email (tech@lamotte.com) for
a return authorization number.
