If any faults or abnormalities are observed, take the instrument out
of service and ensure that it cannot be used until it has been
checked out.
∗
It is recommended to remove the battery from the instrument if not
used.
1.2 Protection mechanisms
This instrument is fitted with various mechanisms :
∗
Varistor protection for limiting transients of over 600 V at the VΩ
terminal, particularly 6 kV pulse streams as defined by the French
standard IEEE 587.
∗
A PTC (Positive Temperature Coefficient) resistor protects against
permanent overvoltages of up to 600 V during resistance,
continuity and diode test measurements. This protection is reset
automatically after overload.
∗
Two HBC fuses provide protection up to 600 V during measure-
ments of intensity type.
∗
An IP protection rating of 40.
1.3

Safety mechanisms

∗
The battery and fuse unit cannot be accessed without first
disconnecting the measuring leads.
∗
If the maximum range is repeatedly exceeded, an intermittent
audible signal warns the user in all functions, except in Ω,
and Hz functions.
