Product information
Description
Specifications:
Measuring accuracy: ±0.1%
Display mode: 0.56" LED
Display refresh rate: > 3 times/s
Working power supply: DC8-24V, 30mA;
Measuring range: 10-9999RPM
Hall effect proximity switch: magnetic appearance
size: 80 x 42 x 25mm/3.14 x 1.65 x 0.98in
LED display (optional): red, blue
Weight: 80g (red), 105g (blue)
Out-of-range display: the first one displays "1" or "-1", and the last three do not display
Precautions:
1. Connect the plug correctly according to the wiring diagram
2. Should avoid strong electromagnetic interference and it is better to use shielded wire or double stranded wire to measure conductors
3.The counter count signal and the switch of the compensation signal input to zero or the circuit should be as close as possible to the counter terminal to make the signal line as short as possible 4. Avoid with others such as: high voltage wires or power wires and so on with the same tube or twisted and nbsp; draw the line, in order to avoid unnecessary interference. If necessary, please use the shielded wire, the shielding layer connects the "+". counting terminals
5. It is not recommended to use a mechanical switch or micro switch because they have a relatively short lifespan and may be miscounted after a long time.If you must, try better quality models, strongly suggest magnetic control switch
