Charging the Battery
Expected time required for charging: approx. 4.5 hours
The battery pack is charged by mounting it in the GL240, attaching AC adapter to the GL240.
(1) Mount the battery pack in the GL240 (see "Mounting the Battery Pack" in the previous page for the
mounting procedure.).
(2) Turn on the power to the GL240. (Please see "2.4 Connecting the Power Cable and Turning on the Power").
(3) The CHARGE LED lights.
•
GL240 is equipped with a temperature monitor function which starts automatic charging as soon as
it is cooled down. Therefore, depending on the internal temperature, charging may not be performed
immediately.
•
The operating temperature range during charge is from 15 to 35°C.
•
When charging is attempted while the power is ON, charging may not be performed immediately even if
the temperature environment conforms to the specification. In such a case, set the Screen Saver settings
to ON or perform charging while the power is OFF.
•
During data capture, when the battery capacity is lower, the file is closed automatically.
•
When using with the AC adapter, the GL240 is automatically battery-powered in case of power outage.
•
During the power is supplied directly from the DC power without using the AC adapter, when the DC
voltage is 16V or less, the battery charge is disabled.
•
The running time depends on the operating environment.
When the empty battery is charged in the GL220/820/900, the charging in about 80-90% will stop. Once
disconnect and connect the AC adapter, or remove and insert the battery pack. The battery pack charging
is started in order to charge up to 100%. (It depends on the remaining capacity.)
