Product Specifications:

Working power supply: AC/DC8-24V, 40mA
Display mode: 0.56 red LED, four-digit reading Measuring range: 10-9999
Measurement accuracy: ±0.1%, reading ±1 digit display refresh rate: >3 times/second
Over-range display: The first digit displays "1" or "-1", and the last three digits do not display.

Precautions for use:
1. Connect the plug correctly according to the wiring diagram
2. The Hall switch is NPN normally open type, and the detection distance of the Hall switch needs to be within 10mm. The installation diameter of the Hall switch is 12mm, and the wire length is within 1 meter.
3. Strong electromagnetic interference should be avoided. It is best to use shielded wires or twisted pairs for measurement wires.
4. The switch or circuit for the counting signal and clearing signal input of the counter should be as close as possible to the terminal of the counter, and the signal line should be as short as possible.
5. Avoid running in the same tube or twisting with other wires such as strong current wires or power wires to avoid unnecessary interference. If necessary, please use shielded wires, and the shielding layer is connected to the counting terminal "+".
6. It is not recommended to use mechanical switches or micro switches, because their lifespan is relatively short, and it is easy to miscount after a long time; if you use mechanical switches or micro switches, please try to use better quality ones to avoid miscounting. It is recommended to use a magnetic switch
