If strong electromagnetic interference is to be avoided, it is better to use shielded wires or double rope wires to measure conductors 2. The counting signal of the counter and the switches of the zero clear signal input or circuit must be as close as possible at the connection of the meter to make the signal line as short as possible 3. Avoid using others such as high voltage wires or power cables etc. with the same tube or twisted pair track line to avoid unnecessary interference. If necessary, please use the shielded wire, shielding layer connect the \"+\" of the counting terminals 4. It is not recommended to use a mechanical switch or micro switch, as they have a relatively short lifespan and may be counted incorrectly after a long time. If you use mechanical switch or micro switch, please try to use better quality so as not to be misunderstood and suggest magnetic control switch Package included: 1 x Speedometer 1 x Hall NPN Proximity Sensor\u003c\/p\u003e \u003ch3\u003e Product Features\u003c\/h3\u003e \u003cul class=\"a\"\u003e \u003cli\u003eThe speedometer uses the latest A\/D converter chip and the reference IC with high stability.
