3. Installation
3.1 Ambient Environment
(1) Do not use the meter in a dusty or vibrating
location. Do not expose it to sunlight or
corrosive gas. Be sure that the ambient
temperature is 10 ~ 40°C and that the
relative humidity is below 90%.
(2) The rear of the meter is equipped with a
cooling fan to keep the internal temperature
down, so adequate ventilation should be
ensured. The meter should be located at
least 10cm from any object or wall behind it.
Do not block the left and right ventilation
holes to keep the meter in good precision.
(3) The meter has been carefully designed to
reduce the noise from the AC power source.
However, it should be used in an
environment with lowest noise as possible.
If noise is inevitable, please install a power
filter.
(4) The meter should be stored within the
temperature range of 0°C ~ 50°C. If the
unit is not going to be used for a long time,
please store it in its original box or a similar
package and keep it from direct sunlight and
humidity.
