Notes:
No device inside can be adjust by user.
When installing and using, there should be tight enough for each connection line, to avoid from any bad connection which would cause heating to damage the meter. Make sure of the right connection of input and output. Please install the meter on local where is dry and ventilated. Don’t put in the place under direct highlight, especial for infrared window. When using infrared communication, it should take more attention to avoid from any disturb from highlight to infrared interface, and please adjust the distance and angel of infrared, to make sure of reliable communication.
Safety precautions:
* Use only isolated tools.
* Place the meter only in dry surroundings.
* Make sure the used wires are suitable for the max current the
meter can measure.
* Make sure the AC wires are installed correctly before activating
the current/voltage.
* Do not touch the meter connecting clamps directly with your bare
hands, with metal, blank wire or other material as you will have
the chance of an electricity shock and a possible chance for health
damage.
* Make sure the protection cover is placed after installation and
has been sealed.
* Installation, maintenance and repair should only be done by a
certified electrician.
* Never break the seals or open the front cover as this might
influence the functionality of the meter.
* Do not through, drop, kick or other physical violence to the
meter as there are high precision components inside that will break
or make the meter measure inaccurate.
* Do not mount the meter in area's with harm gas, dust, mildew or
insects or on unstable surfaces.
