Features ACCURATE AND CONVENIENT: This counter using magnet induction, simple and convenient installation, bring accurate counting EASY BATTERY REPLACEMENT: Using ordinary AA batteries(not included), no external power supply is required, and the battery is easy to replace SEISMIC PROOF AND STABLE: Adopt seismic proof design, effectively ensure the stable and reliable operation of the system NO WEAR AND RELIABLE: No mechanical wear, support reliable operation and long service life, you can use with confidence VARIOUS APPLICATION: 0‑99999 5 digit digital display magnetic electronic counter is suitable for punch, machine tool, assembly line 1. The signal lines for counting and clearing input should be as short as possible, and avoid strong current or power line wiring to avoid unnecessary interference; if necessary, please use shielded wires, and connect the shielding layer to the counting terminal +. 2. Counting signals and reset signals can only be input to non-voltage contact signals, and other electrical signals cannot be input. 3. The operating temperature of the magnet cannot exceed 70 degrees Celsius. If the temperature is too high, the magnetism disappears and induction fails. 4. When the screen display is blurry, please replace the battery with a new one; when it is not used for a long time, you can take out the battery to prevent the battery from deteriorating, leaking, and damaging the counter. 5. Use ordinary AA batteries and do not connect to external power (external power will damage the counter); the power consumption of the counter is ultra-low, so there is no need to press pause or switch to turn off the counter every day to save power. 6. If the counter is abnormal, it can be restarted. Method: Remove the battery, install the battery in the opposite direction, then remove the battery, and install the battery in the standard direction.
