Display mode: 0.56 inch LED.\nDisplay update rate: \u0026gt; 3 times\/sec. Operating power supply: DC8-24V, 30mA,\nmeasuring range: 10-9999RPM Hall proximity switch: magnetic. Appearance size:\n80 x 42 x 25 mm \/ 3.14 x 1.65 x 0.98 inches. LED indicator (optional): red,\nblue. Weight: 80 g (red), 105 g (blue). Over range display: the first display\nshows \"1\" or \"-1\" and the last three are not displayed Precautions: 1. If\nstrong electromagnetic interference is to be avoided, it is better to use\nshielded wires or double wire wires to measure conductors 2. The counter\nsignal and the switches of the zero extinguish signal input or circuit must be\nas close as possible to the terminal of the counter to make the signal line as\nshort as possible 3. Avoid using others such as high voltage wires or power\ncables etc. with the same tube or twisted track line to avoid unnecessary\ninterference. If necessary, please use the shielded wire, shielding layer\nconnect the \"+\" of the counting terminals 4. It is not recommended to use a\nmechanical switch or micro switch as they have a relatively short service life\nand can be counted incorrectly after a long time. If you use a mechanical\nswitch or micro switch, please try to use a better quality so as not to be\nmisunderstood, and suggest a magnetic control switch Package includes: 1 x\nspeedometer. 1 x Hall NPN Proximity Sensor\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eThe tachometer uses the latest A\/D converter chip and reference IC with high stability.
