Battery Charging
The TR-3 has a built-in 3.6V/2.5AH Ni-MH battery. When fully charged,
it can be used for over four hours.
When the battery Voltage drops below 3.2V, the battery symbol
at the top of the display screen will have no bars displayed. When the
Voltage drops below 3.1 V, the TR-3 shuts off automatically to protect
the battery. The battery will need to be recharged.
To charge the TR-3’s battery, connect the charge cube to the charge
socket on the bottom of the meter and plug the charger into an AC
outlet.
While charging, the LED on the TR-3 front panel will have a RED light.
The TR-3 should be charged for 12 to 14 Hours for a full charge.
The battery MUST be charged with the Trilithic
charge cube provided with the TR-3. Using any
other charge cube may damage the battery.
