Seven, matters needing attention

1, the line must be shielded wire, and the power cord, the input line and the output line must be separated.

2, the use of the environment should be no conductive dust and non corrosive metal and the destruction of insulating gases exist, altitude less than 2500 meters.

3, the factory has been adjusted zero and precision, please do not adjust.
