BATTERY/AC OPERATION
The 2020t/i BLE 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 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
rubber USB port plug after charging. Failure to insert the USB port plug when the meter is
not connected to a computer by USB or actively charging by USB could result in damage to
internal components.
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. Failure to insert the USB
port plug when the meter is not connected to a computer by USB or actively charging by
USB could result in damage to internal components.
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 6 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 wall adapter will charge the unit continuously. Storing the meter
above ambient room temperature will decrease the battery charge more quickly than
storage at room temperature. If the meter does not turn on, it means that the battery is at
a very low charge. Charging the battery with the wall adapter in this state may take up to 10
hours. At low temperatures, approaching 0 °C, the battery will charge more slowly. It will not
charge at all below 0 °C.
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. When the
battery icon simultaneously flashes bars 1 and 2 followed by bars 3 and 4, it is an indication
that the battery is damaged and technical support should be contacted.
To extend the life of the battery:
• 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 at a moderate temperature.
• Fully charge the battery before storing the unit for extended periods of time.
• Fully charge the battery at least once per year. Failure to do so may result in a
permanently drained battery.
• Limit backlight use. The unit consumes three times the normal power when the
backlight is 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 should be replaced. Contact LaMotte Company by phone (1-800-344-
3100) or email (tech@lamotte.com) for more information.
