LCD Digital Electrical Counter 5 Digit Display Accumulation with Magnetic Switch Sensor Punch Machine Meter

Sensors AmmetersAttention: 1. The count signal of the counter and the switch or circuit for clearing signal input should be as close as possible to the terminal of the counter. The signal line should be as short as possible. 2. Avoid using other cables such as strong wires or power wires to avoid unnecessary interference. If necessary use a shielded cable and connect the shielding layer to the "+" terminal. 3. The count signal and the clearing signal can only input the contact signal and can not input other electrical signals. 4. The contact input should be reliable so as to avoid miscounts due to contact rebound and incorrect clearing. 5. When the LCD display is blurred replace the battery with a one. When it is not used for a long time remove the battery to prevent the battery from spoiling and damage the counter. After removing the battery press the PAUSE key to make the screen display disappear to turn off the counter's internal auxiliary battery. 6. It is not recommended to use mechanical switches or microswitches because their life is relatively short and it is easy to miscount after a long time. According to the actual situation the switch should be replaced at the right time. If using a mechanical switch or a micro switch please Try to use better quality so as not to miscount it is strongly recommended to use magnetic switch. 7.If you need a switch please choose "Switch Only"(No counter); If you need a counter and a switch please choose "Counter and Switch".
