Battery
Charging the battery requires a common 9VDC adapter (positive pole located inside the female connector) supplied with the analyzer
and a convenience outlet. The analyzer’s charging circuit accepts 9VDC from any standard AC 110V or 220V adapter. The electronic
design enables the analyzer to remain fully operable during the 8-10 hour charging cycle.
Procedure:
1. Unless the analyzer is to be operated while charging, turn the analyzer OFF when charging the battery for the shortest charging
cycle.
2. Connect the appropriate 9VDC adapter supplied with the analyzer to a 110V or 220V outlet.
3. Insert the male phone plug from the 9VDC adapter into the integral female CHARGE jack located on the bottom of the enclosure.
4. Caution: The analyzer is designed to operate in the charging mode, however, operating the analyzer in hazardous or explosive
atmospheres while charging the battery IS NOT recommended.
Service: A single charge is sufficient to operate the GPR-2000 Series analyzers continuously for a period of 60 days. Expect 8-10 hours
of service if the integral sampling pump of the GPR-2000P Series analyzer is operated continuously.
Warning indicators:
An LED indicator located on the front panel will light continuously during the CHARGE cycle.
A second LED indicator located on the front panel provides a blinking 72 hour warning LOW BATT of the need to recharge the battery.
Caution: Operating the analyzer beyond this 72 hour warning may permanently damage the battery.
