Usage

The public terminal and the counting terminal will be connected once and counted once; and when it is connected for more than 0.5 seconds, the LCD screen will display "OK" signal indication mark.

Magnetic induction switch can be selected, or other switches can be selected according to the actual situation, such as micro switch, travel switch, electronic switch (no voltage contact counting).

Notes and special instructions.

1. Counting and zeroing signals can only be inputted as non-voltage contact signals, no other electrical signals can be inputted.

2. The contact input should be reliable, so as to avoid false counting caused by contact jumping back, jittering, poor contact, and so on.

3. Avoid the same pipe or stranded wires with strong electric wires or power wires to avoid unnecessary interference.

4. Use two AAA batteries, never external power supply (external power supply will damage the counter).
