Operating voltage: DC8-24V, 30mA, Measuring range: 10-9999RPM Hall proximity switch: magnetic Appearance Size: 80 42 25mm \/ 3.14 1.65 0.98in LED display (optional): red, blue Weight: 80g (red), 105g (blue) Handover display: The first display shows \"1\" or \"-1\" and the last three are not displayed. Precautions: 1. 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 to the terminal of the counter to make the signal line as short as possible. 3. Avoid using others such as high voltage wires or power cables and so on with the same tube or twisted rail line to avoid unnecessary interference. If necessary, please use the shielded wire, the shield connects the \"+\" of the meter terminals. 4. It is not recommended to use a mechanical switch or micro switch as they have a relatively short lifespan and may be miscounted 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.
