Warning

Please read before using instrument
Do not measure on live parts.
Observe permissible storage and transport temperatures and the permissible oper-
ating temperature (e.g. protect measuring instrument from direct sunlight)!
Switch off the instrument when changing the configuration (e.g. probe change, plug-
ging in the V24 cable) because the values specific to the probes can only be read
after the instrument is switched on.
If the instrument is opened, improperly handled or force is used the warranty rights
are cancelled.
In the case of temperature probes which come into contact with metal, there may
be an electric discharge caused by the different potential between metal and the
surface probe. Please apply adhesive tape to the point of measurement during
this type of application. In this way a discharge which could limit the functioning
of the instrument is preventde.
