Common errors in use

4 Digital LED Tachometer RPM Speed Meter+Hall Proximity Switch Sensor

Please note that the instrument only feeds back the detected correct working state, and will not process the data. The test data jumps too much. Please check whether the test object rotates at a constant speed and the installation is stable.

Note:

  • Please note that the new and old models are shipped randomly, and make sure you will not mind before ordering.

Matters needing attention:

  • 1. Connect the plug correctly according to the wiring diagram.
  • 2. Hall switch is NPN normally open, and the detection distance of Hall switch should be within 10mm. Hall switch is installed with a diameter of 12mm and a line length of less than 1m.
  • 3. Strong electromagnetic interference should be avoided. It is best to use shielded wire or twisted-pair wire for measuring wires.
  • 4. The input switch or circuit of the counter's counting signal and reset signal should be as close as possible to the terminal of the counter, and the signal line should be as short as possible.
  • 5. Avoid being in the same tube or twisted with other wires, such as high-voltage wires or power wires, so as to avoid unnecessary interference. If necessary, please use shielded wires, and the shielding layer is connected to the counting terminal "+".
  • 6. It is not recommended to use mechanical switches or micro-switches, because their service lives are relatively short and they are easy to count by mistake after a long time; When using mechanical switches or microswitches, please try to use better quality ones to avoid false counting. It is strongly recommended to use magnetic switches.

DO NOT ORDER TERRIBLE PRODUCT AND WORSE CUSTOMER SERVICE.Installed easily, but does not work. It just flashes HHHH or LLLL or random numbers. The pick up seems to flash when the magnet passes by, but the read out doesn't show anything. I've already installed this in a remote location, and do not have the original packaging. I'm very displeased with this product and the time it has wasted. I'd like my money back! I wish I could get paid for the time wasted too!Update:I was told I’d get a replacement part. After waiting for one to show up a couple weeks, the replacement was cancelled. DO NOT ORDER!

Easy install, works perfectly, great value. I used this to display the spindle speed on my wood lathe.
