Specification: Item Type: Punch Electronic Counter Material: ABS Battery Model: 1.5V AA battery (not included) Counting Range: 0-99999 Count Maximum Frequency: 20HZ Counting Minimum Pulse Width: 1MS Clear Minimum Pulse Width: 1S Magnet Induction Proximity Distance: Approx.10-15mm/0.4-0.6in Magnetic Induction Connection Distance: Approx.≥35mm/1.4in Package List: 1 x Punch Electronic Counter 1 x Magnetic Induction Switch 1 x Magnet 1 x Bracket Note: 1. The signal line for counting and clearing input should be as short as possible, avoid wiring with strong electricity or power lines cause unnecessary interference, if necessary, please use shielded lines, the shielding layer connect to the counting terminal +. 2. The counting signal and clearing signal can only input the contact signal without voltage, other electrical signal can not 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 blurry, please replace the battery with a new one. 6. When not in use for a long time, please press the pause/power key to turn off the counter and auxiliary battery, can take out the battery together to prevent the counter from deteriorating and leaking. 7. Use an ordinary AA battery, never connect an external power supply, the external power supply will damage the counter, when the power consumption of the counter is extremely low, you don't have to press the pause/power key to turn off the counter every day to save power. 8. If the counter is abnormal, you can restart the machine. Method: Take out the battery, install the battery in the opposite direction, then take out the battery, and then install the battery in the standard direction.
