Precautions:
-
Should avoid strong electromagnetic interference and it is better to use shielded wire or double stranded wire for measuring conductors
-
The counting signal of the counter and the switch of the zero clearing signal input or the circuit shall be as close as possible to the terminal of the counter to make the signal line as short as possible
-
It is not recommended to use a mechanical switch or micro switch because they have a relatively short life span and can be counted by mistake after long time. If you use a mechanical switch or a micro switch, please try to use a better quality, so as not to miscount, and strongly suggest a magnetic control switch
