9 Care and Maintenance
9.1 Test Device, Probe and Cable
From time to time, wipe the tester, probe and cable with a damp, but not moist cloth, e.g. microfiber
cloth. Under no circumstances, chemicals or cleaning agents should be used.
9.2 Screen
Do not use any sharp objects, chemicals or detergents for cleaning, since the protective foil could be
destroyed. Please use moist lens cleaning cloths instead. A protective film is attached in order to
protect the touch-sensitive touch screen. If it contains severe stains or scratches, the protective film
can be replaced by a new one.
9.3 Batteries
The batteries are nearly maintenance-free, if they are used in the specific environmental area.
However, you should observe the following instructions:
Prior to initial commissioning and after it has been stored for more than 2 months, the
battery needs to be fully charged.
The device is featured with an intelligent charging system to ensure that there is no danger
of overcharging, even if it has been connected for a longer period of time. However, we are
recommending that you disconnect the unit from the mains supply upon after completion of
charging.
Safety Information:
Batteries must never be exposed to temperatures exceeding the specified operating or storage
temperatures!
The plug-in power supply may only be operated in dry areas!
