Note:
1. If you want to avoid strong electromagnetic interference, it is recommended to use shielded wire or double rope wire to measure the conductor
2. Counter count signal and zero clear signal input or circuit switch should be as close as possible to the counter terminal to shorten the signal line.
3. Do not use high pressure wires or power cables on the same tube or twisted track to avoid unnecessary interference. Use shielding wire as needed, shield layer connects "+" of count terminal
4. It is not recommended to use mechanical switch or micro switch. These switches are relatively short life and can be accidentally counted over a long period of time. If you use a mechanical switch or micro switch, please use better quality and suggest a magnetic control switch to avoid misunderstanding.
