Before Using The CRT-400
Before Charging, Disconnect Any Test Leads
Before charging the battery, disconnect any test leads. Open the accessory compartment cover by
loosening the two slotted screws. Connect the charger to the power connector inside the accessory
compartment located on the back of the CRT, then plug in the charger. When charging is complete, the
green LED will turn off.
Charge Complete
When the battery is fully charged, the green LED goes off upon charging completion, unplug the charger
from the power source and then unplug it from the CRT–400. Replace the accessory compartment cover
before beginning test.
Note: The life of the battery depends on how well it is charged. Please refrain from leaving the CRT in
extreme cold or hot temperatures. Subjecting the CRT to extreme temperature conditions will shorten
the life of the battery.
CAUTION: Never store the CRT–400 in a discharged condition. If you use a unit needing recharge,
it will shut down without warning.
Low Battery
When the battery is low, warnings indicate remaining test time. At full discharge, the unit turns off. You
can access data in temporary storage after recharging.
Note: The CRT–400 shuts down if inactive for ten minutes to prolong battery life.
WARNING: If the battery wears down during testing, do not use the charger for power when
testing cells.
WARNING: Injury to personnel or damage to equipment could result.
