Charging the Lithium-Ion Batteries
•
Ensure the instrument is dry.
•
Plug the data cable into the instrument.
•
Plug the charger into the data cable.
•
Plug the charger into a 120 or 240 volt AC outlet and allow the instrument to charge until the
green flashing light on the charger turns solid green. A full charge requires approximately 3
hours.
o
If the light on the charger is off, the battery is not attached correctly.
o
If the light on the charger is solid yellow, the battery is on standby.
o
If the light on the charger is flashing red, an error has occurred.
The charger should be connected to the instrument
before
plugging the charger into the AC
outlet for proper operation of the charger and charging light.
•
Turn the instrument off after charging (unplug the data/power cable) to maintain a full charge
after charging.
•
If instrument is left turned on after the battery has been charged to 8.3 volts, the charger will
turn off and the instrument will start drawing on the battery. When the battery voltage drops
below 8 volts the charger will automatically turn on and start charging the battery up to 8.3
volts. The charger can be restarted by manually resetting it (refer to procedure below).
•
It is possible to use the instrument while charging the battery, however, instrument use
causes the power consumption to fluctuate which can confuse the charger and cause it to
stop charging prematurely. The charger monitors the charging power to detect when the
battery is charged; fluctuating power from the instrument can corrupt the algorithm. To
ensure proper charging, manually reset the charger when you have stopped using the
instrument (refer to procedure below).
•
To manually reset the charger
: unplug the charger from the wall and then back in. This will
reset the charger and start charging the battery.
