Charging the Battery
w Before you use the calibrator for the first time,
charge its battery pack in the external battery
charger. The Model BC7217 charger charges both
the NiMH and Ni-Cd battery packs.
Figure 9 shows how to remove the battery. Remove
the battery door and tap the calibrator with your
hand to get the battery out. Place the battery in the
charger and connect the charger to line power. The
charger automatically senses line voltage and
adjusts itself accordingly.
A discharged battery is fully charged in 2 hours or
less in fast-charge mode (steady indicator light on
the charger). Full charge is maintained after that
time in trickle-charge mode (blinking indicator light
on the charger). Switching between charging modes
is automatic. You can leave the battery pack on
trickle charge indefinitely without damage.
Note
When you remove a charged battery from
the charger, wait for the blinking indicator to
go off before you insert a discharged
battery. It takes about 2 seconds for the
battery charger to reset.
