Test-Um NT955 Series ValidatorTM Battery and Power Management

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.
