LCD Display: The digital counter uses a large five-digit LCD display with ultra-low power consumption. The screen is large and clear even after prolonged use. Easy to Use: Press the count/pause button (pause) to stop counting. After 0-30 seconds, the LCD screen will automatically turn off and enter sleep mode. Press the count/pause button again to turn on the indicator light and continue counting. Digital Counter: The magnetic induction counter adopts the principle of magnetic induction and is easy to install. The maximum counting speed of the counter is: 20 times per second, and the counting is accurate. Shockproof: The digital counter adopts shockproof technology to ensure stable system operation, reliable operation and long service life. Battery powered: The digital counter uses ordinary AA batteries, no external power supply required, no mechanical wear, safe operation and long service life. Specifications: Power supply: 1.5V-AA battery (not included) Available ambient temperature: -5-40C Distance within magnetic induction: about 5-10mm Hole size: about 63*35mm/2.5*1.4in Application method: 1. Start counting: Connect the magnetically controlled induction switch to the counting terminal, according to the requirements of actual operation, flexibly assemble the magnetic induction switch and the magnet on the appropriate positions of the device, and then count once, meanwhile, make the magnet. Approach and leave the magnetically controlled induction switch once. 2. Pause counting: Press the Count/Pause key (Pause) to pause the counting. According to the working states of the counter, the LCD indication of the counter will turn off within 0-30 seconds and enter the standby state (the power consumption is almost close to 0); Press the Pause key again to turn on the LCD indicator and continue counting. 3. Reset: Press the Reset button directly; Note: When resetting, whether the counter is in the start state or in the standby state (the LCD has no indication), the data will be cleared and the LCD indication is 00000. 4. Only the counting signal and the reset signal can be input with the contact signal, other power signals are not allowed. 5. The working temperature of the magnet should be lower than 70 degrees, too high temperature will cause loss of magnetism, thus invalidating the induction.
