Safety precautions and procedures This instrument conforms with safety Standard EN 61010-1 related to electronic measuring instruments. For your own safety and to avoid damaging the instrument follow the procedures described in this instruction manual and read carefully all notes preceded by this symbol .

CAUTION For your own safety and to avoid damaging the instrument follow the procedures described in this instruction manual and read carefully all notes preceded by this symbol .

Do not touch exposed metal parts such as test lead ends, sockets, fixing objects, circuits etc. „ Avoid doing that if you notice anomalous conditions such as breakages, deformations, fractures, leakages of battery liquid, blind display etc. „ Be particularly careful when measuring voltages exceeding 20V to avoid risks of electrical shocks.

How to test the 3 phases of AC Let your crocodile clip clamp the 3-phase power terminal. In each test, hold the power button and check the indicators on the panel. „ If L1, L2 and L3 are lit, it means normal. (In this case, skip to step 2.) If one of them remains unlit, L1 for example, it means the wire for L1 is disconnected or in power failure mode. You may check visually or with a multimeter if the wire is connected well.
