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.
