Charging the Battery
Caution:
The provided battery charger is designed to work safely with this device. Do
not attempt to connect any other charger or adapter to this device. Doing so
may result in equipment damage.
To charge the battery, connect the battery charger to an AC power outlet and the DC
barrel connector to the socket on the right side of the GT-521S. The battery charger is
universal and will work with power line voltages of 100 to 240 volts, 50 to 60 Hz. A
discharged battery pack will take approximately 2.5 hours to fully charge.
When fully charged the battery inside the GT-521S will power the unit for about 6 hours
of continuous sampling. Under normal operation, the battery will power the unit for
about 24 hours. For continuous operation, operate the unit with the battery charger
attached. Charge the battery before storing the GT-521S. Storing a discharged battery
will degrade its performance.
