Specification: Item Type: Electronic Counter Material: ABS Battery Type: 1.5V AA battery (not included) Counting Range: 0-999999 Counting Highest Frequency: 20HZ Counting Minimum Pulse Width: 1MS Clear Minimum Pulse Width: 1S Package List: 1 x Electronic Counter Note: 1. The signal line for counting and clearing input should be as short as possible to avoid wiring with strong electricity or power lines to avoid unnecessary interference; if necessary, please use shielded lines, and the shielding layer is connected to the counting terminal +.2. Only the contact signal without voltage can be input to the counting signal and the clear signal, and no other electrical signals can be input.3. The sensing distance is related to the magnetic size of the magnet. You can change the sensing distance by changing different magnets.4. The use temperature of the magnet cannot exceed 70℃. If the temperature is too high, the magnetism will disappear and the induction will fail.5. When the screen display is blurred, please replace the new battery; when not in use for a long time, please press to pause switch the machine to turn off the counter and auxiliary battery; you can also take out the battery together to prevent the battery from deteriorating and leaking and damaging the counter.6. Use an ordinary AA battery, never connect an external power supply (external power supply will damage the counter); the power consumption of the counter is ultra low, and you do not have to press the pause switch to turn off the counter every day to save power.
