1.4.5 Precautions for Usage
Please do not use the tester in dusty, vibrative, direct sunlight and corrosive gases and other adverse
environments.
When the instrument is not used for a long time, please put it in the original box or similar box and stored in
a ventilated room with temperature of 5
℃
~40
℃
and relative humidity less than 85% RH. Do not store the
tester in a corrosive atmosphere containing harmful impurities and should avoid direct sunlight.
The instrument has been carefully designed to reduce clutter due to AC power input. However, it should still
be used under low noise conditions. If that is inevitable, please install the power filter.
