Precautions:
1. The counting signal of the counter and the input switch or circuit of the clear signal should be as close as possible to the terminal of the counter, and the signal wire should be as short as possible.
2. Avoid the same tube or twisted wiring with others, such as strong current wires or power wires, to avoid unnecessary interference. If necessary, use shielded wires and connect the shielding layer to the counting terminal +.
3. Counting signal and clearing signal can only input contact signal, not other electrical signals.
4. The contact input should be reliable to avoid false counting and false zeroing caused by contact bounce.
5. When the LCD display is blurred, please replace with new batteries. When not in use for a long time, please remove the battery to prevent battery deterioration and leakage to damage the counter. After removing the battery, press the count/pause key (PAUSE) to make the screen display disappear to turn off the auxiliary battery inside the counter.
