1. General instructions
This digital clamp meter has been designed according
to International Electro Safety Standard IEC-61010
concerning safety requirements for electronic
measuring instruments and hand-held current clamps;
meeting the requirements for 600CAT.II of IEC-61010
and grade 2 for pollution.
Before using this meter, please read carefully this
user's manual and respect the related safety precautions.
2.1 Precautions for use

be replaced, a new one with the same model or same
electric specification should be adopted.
• If the meter is placed in a relatively noisy environment,
meter readings will become unstable, even with big
errors.
• Before changing the measuring range, you must
ensure that the test lead is not connected to any
circuit to be tested.
• When you can’t determine the size range of signal to
be tested, please switch the measuring range to the
maximum position.
• When you use the meter to measure, you should make
the test lead and the rotary switch in the correct position.
• When use the test lead to measure, you should keep
