Measurement range: Frequency: 9999Hz, 999.9 HZ, 99.99 KHZ, automatic switching selection. Automatic range selection saves user time and effort. Efficient completion of work.

Specifications: Measurement Accuracy: ±0.1% Display Mode: 0.56" LED Display Update Rate: ＞3 times/s Operation Power: DC8-24V, 30mA, Measuring Range: 10~9999RPM Hall Proximity Switch: Magnetic Appearance Size: 80 x 42 x 25 mm/3.14 x 1.65 x 0.98 inch LED display (optional): Red, Blue Weight: 80g (red), 105g (blue) Overrange display: The first display shows "1" or "-1", the last three are not displayed

Notes: 1. If you want to avoid strong electromagnetic interference, it is recommended to use shielded wire or double rope wire to measure the conductor. 2. The count signal and zero clear signal input of the counter or the switch of the circuit should be as close as possible to the terminal of the counter to make the signal wire as short as possible. 3. Avoid using high voltage wires, power cables, etc. in the same tube or twisted tracks to avoid unnecessary interference. If necessary, please use shielded wire, the shielding layer connects the "+" of the count terminal 4. It is not recommended to use mechanical switches or microswitches. These switches have a relatively short lifespan and can be miscounted after a long period of time. If you use mechanical switch or micro switch, please use better quality and suggest magnetic control switch to avoid misunderstanding Delivery content: 1 x Speedometer 1 x Hall NPN proximity sensor
