۱٫ Connect the plug correctly according to the wiring diagram.
۲٫ Should avoid strong electromagnetic interference, and it is better to use shielded wire or double-stranded wire to measure conductors
۳٫ The counter count signal and the switch of the reset signal or circuit input should be as close as possible to the counter terminal to make the signal line as short as possible.
۴٫ Avoid using cables such as
