Battery Test
The LC103 has a built-in battery test feature that shows
the remaining battery charge. A reading of 100%
indicates that the battery is fully charged. As the battery
charge is used up, the reading will drop. The low battery
circuits will turn the unit off shortly after the battery test
reading drops to 0%, and before the battery, level drops
too low for reliable operation. The LC103 never fully
discharges the battery, which helps extend the life of the
BY289.
To perform the battery test:
1.
With a BY289 installed, press and hold the POWER
button.
2.
Read the graph and numerical percentage of
remaining battery charge in the DISPLAY.
3.
If the reading shows 0%, the unit may not operate, or
operate for just a short time since the low battery
circuit turns the LC103 off at this battery level.

remaining battery charge.
Recharging the Battery
The BY289 battery should never be allowed to remain
discharged for more than a few hours, since this will
shorten its lifetime. The battery must be recharged
whenever the battery test reads 0%. However, you
should recharge the battery more often than this to
lengthen the battery's lifetime and keep the LC103 ready
for portable use at all times.
To recharge the battery, simply leave it installed inside
the LC103 while the unit is connected to the AC Power
Adapter and the Power Adapter is connected to a source
of AC power. The charging time required to return the
battery to 100% depends on how far it is discharged. The
battery will trickle charge while the LC103 is in use and
powered from the AC adapter, but it will recharge the
quickest if the POWER is turned off. Normally, a battery
will completely recharge in about 8 hours with the
POWER off.
To operate the LC103 using the optional BY289
battery:
1.
Install the BY289 battery into the LC103 battery
compartment.
NOTE: If you are using the BY289 for the first time,
be sure to charge the battery before using the LC103.
Though factory tested, the BY289 may not be charged
when you receive it.
2.
Press the POWER button and release. The
WARNING LED will momentarily blink to indicate
it is operational and the displays will read “LC103
ReZolver” and “Ready.”
3.
The LC103 is immediately ready for use. If precise
measurements are required, allow the unit to operate
for 20 minutes to reach specified accuracy.
Auto-Off
To conserve battery charge, the LC103 contains an auto-
off circuit. This circuit keeps the batteries from running
down if you should forget to turn the unit off, but keeps
the ReZolver powered up during use. The auto-off
circuit will shut the LC103 off after approximately 5
minutes if none of the front panel buttons have been
pushed. Pressing any COMPONENT TYPE button,
COMPONENT PARAMETERS button, COMPONENT
TEST button, or the POWER button resets the auto off
circuits. The auto-off circuits are bypassed when the
LC103 is operated from the AC Power Adapter.
