Note:
1, Connect wires correctly according to the wiring diagram.
2, Strong electromagnetic interference should be avoided, measuring had better to be shielded cable or twisted-pair cable.
3, Counting and reset input switch or circuit should be near the counter terminals, making cables as short as possible.
4, Avoid wiring in same tube or twisted with high voltage electric wire or power wire, in order to avoid unnecessary interference. If necessary, please use shielded cable, shielding layer on the counter terminal "+".
5, Mechanical switch or microswitch is not recommended, because of their relatively short life may cause mistakes after long time use.If using mechanical switch or microswitch, please try to use ones of better quality, in order to avoid error count. It is strongly recommended to use magnetic control switch.
