3.9 Charging of Testing Computer
Only the charging equipment supplied by the manufacturer should be used for charging the battery. To
charge the battery of the testing computer, plug the power cable into the ‘12 V /max. 1.25 A’ socket on
the testing computer. This socket is located on the top left of the control panel, next to the GPS antenna.
Depending on ambient temperature, charging time is approximately 4-5 hours, when the battery is empty.
The current battery charge will be shown during ‘STATUS REQUEST’, when switching on the testing
computer. The maximum variation in voltage must not exceed 10%. During the charging process place
the testing computer inside a dry room and take care that it is possible to disconnect the device from
power at any time.

cable with LEMO-plugs, and plug it into the LEMO-socket on the sensor dome. Depending on ambient
temperature, charging time is approximately 8 hours, when the battery pack is empty. The current battery
charge will be shown as a percentage below the battery charge of the testing computer during ‘STATUS
REQUEST’, when switching on first the load plate and subsequently the testing computer. The maximum
variation in voltage must not exceed 10%. During the charging process, place the load plate inside a dry
room and take care that it is possible to disconnect the device from power at any time.
