Otherwise current surges may arise when the circuit is made or
broken and these could blow the fuses or damage the switch or the
sockets and terminals.
When checking out a television or power switching circuits (swit-
ched mode power supplies, circuits including thyristors and triacs,
etc.) high-amplitude voltage pulses at the test point may damage
the multimeter. The use of a TV filter probe, type HA0902, protects
the multimeter by attenuating any such pulses.
Resistance measurements should never be made on a live circuit.

The MX 20 multimeter features the patented SECUR’X system
which prevents inadvertant unplugging of the test leads, and adds
to the degree of protection already provided by the leads themsel-
ves. The SECUR’X system is not an integral part of the instrument
and can be removed if necessary, particularly for access to the
battery and fuses.
The system, which is extremely simple to use, permits effortless
insertion of the banana plug. The latching effect is obtained by
means of grooves on the plug body.
To unlatch a lead push the tab forwards and pull on the plug.
