If you have reason to assume that safe operation is no
longer possible, then disconnect the appliance immedia-
tely and secure it against inadvertent operation. It can be
assumed that safe operation is no longer possible if:
- the device shows signs of visible damage,
- the device no longer functions and
- it has been stored for longer periods under unfavoura-
ble conditions or
-following considerable stress during transportation.
Do not switch the measuring instrument on immediate-
ly after it has been taken from a cold to a warm environ-
ment. The condensation that occurs could destroy the
device. Allow the device to reach room temperature
before switching it on.
Do not leave the packaging material lying around
carelessly. Plastic films and/or bags and polystyrene
parts etc. may become dangerous toys in the hands of
children.
Before opening it, disconnect the device from all volta-
ge sources.
Capacitors in the device may still be charged, even if the
device has been disconnected from all voltage sources.
You should also heed the safety instructions in each
chapter of these instructions.
