VOLTCRAFT VC-20 Notice D'emploi page 35

Avoid operation in direct proximity of:
- strong magnetic or electromagnetic fields
- transmitting aerials or HF generators.
These could falsify the value measured.
If you have reasons to assume that the device can no longer be
operated safely, disconnect it immediately and secure it against
being operated unintentionally. It can be assumed that safe opera-
tion is no longer possible if:
- the device is visibly damaged,
- it does not function any longer
- if it has been stored for long periods of time under
unfavourable conditions
- if it has been subject to considerable stress during trans-
portation.
Do not switch the measuring instrument on immediately after it has
been taken from a cold to a warm environment. The condensation
water generated could destroy the device. Allow the device to reach
room temperature before switching it on.
Do not leave the packaging material lying around carelessly since
such materials can become dangerous toys in the hands of children.
You should also observe the safety instructions in each chapter of
these instructions.
