dangerous voltages. Improper handling can therefore result in serious injury or
material damage.
Only use isolated tools suitable for the voltages the meter is used for.
Do not connect while circuit is live (hot).
Place the meter only in dry surroundings.
Do not mount the meter in an explosive area or exposed to dust, mildew
and/or insects.
Make sure the used wires are suitable for the maximum current of this
meter.
Make sure the AC wires are connected correctly before activating the
current/voltage to the meter.
Do not touch the meter’s connection clamps directly with your bare hands,
with metal, blank wire or other conducting material as that will cause an
electric shock and possibly cause injury.
Make sure the protection cover is placed after installation.
Installation, maintenance and repair should only be done by qualified
personnel.
Never break the seals to open the front cover as this might influence the
functionality or accuracy of the meter, and will void all warranty.
Do not drop, or allow physical impact to the meter as there are high
precision components inside that may break and render the meter
measurement inaccurate.
