1. SAFETY PRECAUTIONS AND PROCEDURES
This instrument has been designed in compliance with EN 61010 directive. For your own
safety and to avoid damaging the instrument we suggest you follow the procedures hereby
prescribed and to read carefully all the notes preceded by the symbol
.
WARNING
Should you fail to keep to the prescribed instructions you could damage the
instrument and/or its components or endanger your safety.
Take extreme care of the following conditions while taking measurements:
• Do not measure voltage or current in humid or wet environments.
• Do not use the clamp in the presence of explosive gas (material), combustible gas
(material), steam or dust.
• Do not touch the circuit under test if no measurement is being taken;
• Do not touch exposed metal parts, unused terminals, circuits and so on;
• Do not use the instrument if it seems to be malfunctioning (i.e. if you notice
deformations, breaks, leakage of substances, absence of segments on the display and
so on);
• Be careful when you measure voltages exceeding 20V as you may risk electrical
shocks.
• Take care not to allow your hand to pass over the Safety Guard Fig. 1, pos.2) on
current measurements and voltage measurements using the holster.
The following symbols are used:
Caution: refer to the instruction manual. An incorrect use may damage the tester
or its components

1.1. PRELIMINARY
INSTRUCTIONS
• This clamp has been designed for use in environments of pollution degree 2.
• It can be used for CURRENT measurements on installations of over voltage category
III up to 600V (voltage between phase and earth) and for VOLTAGE and
FREQUENCY measurements on installations of over voltage category III up to 600V
(voltage between terminals and between phase and earth).
• Please use the standard safety precautions aimed at:
