Input pulse signal: NPN\/PNP open collector, contact switch, non-\r\ncontact switch, level pulse 2. Input signal voltage: Low level: -30V-0.6V,\r\nHigh level: 4-30V 3. Measurement range: Speed: 10-9999RPM Specifications: 1.\r\nMeasurement accuracy: ± 0.1%, reading 1 word 2. Display mode: 0.56 blue LED 3.\r\nFour readings 4. Display refresh rate: \u0026gt; 3 times \/ sec 5. Working power: AC \/\r\nDC8-24V, 40MA 6. The external dimensions: 79 × 42 × 32MM 7. Installation size:\r\n76 × 39MM 8. Weight: about 50G 9. Over-range display: the first position shows\r\n\"1\" or \"-1\", the last three digits do not display Precautions for use: 1.\r\nConnect the plug correctly according to the wiring requirements. 2. Should\r\navoid strong electromagnetic interference, the measurement wire is best to use\r\nshielded wire or twisted pair. 3. The counter signal and the switch or circuit\r\nof the clear signal input should be as close as possible to the terminal of\r\nthe counter to make the signal line as short as possible. 4. Avoid with other\r\nwires such as strong electric wires or power wires or stranded wires to avoid\r\nunnecessary interference. If necessary, use shielded wires and the shield is\r\nconnected to the counting terminal “+”. 5. It is not recommended to use\r\nmechanical switches or micro switches, because their life is relatively short,\r\nit is easy to count down after a long time; if using mechanical switches or\r\nmicro switches, please try to use better quality, so as not to count errors,\r\nstrong Recommended magnetic switch.
