Test-Um NT955 Series
Validator-NT Main Unit
When powered on, the Validator-NT reports the charging status at the top
of the screen under the battery icon. A green full battery icon indicates
the battery is fully charged. As the battery discharges, the percentage of
remaining charge is displayed in 10% steps. The battery icon changes
from green to amber when the battery reaches approximately 30% of its
charge capacity.
When the battery is Low, the battery icon will change to red and
begin to flash. An audible warning tone will sound when the battery
reaches approximately 10% of its charge capacity to notify the user
that in approximately three minutes, the Validator-NT will power down
automatically and save the current job.
Note: The battery must be fully charged the first time it is used to re-
port charging status. After one full charge, the batteries in the main unit
and the remote unit are interchangeable.
If the battery is replaced, it is necessary to start a new charge cycle by
either disconnecting the AC adapter momentarily or pressing the Reset
Charge (RST CHRG) soft key (F1) on the Properties/Battery Info screen.
In addition to the charging status, additional information that is useful to
monitor the loss of capacity in the battery over time is displayed on the
Battery Properties screen.
Charging will continue when the Validator-NT is powered off but there is
no visual indication. The Validator-NT has various timeout conditions to
conserve battery life. The specific timeout values are adjustable in the
Setup, Shutdown Timeouts screen.
