## Questions & Answers

**Q: What current input does the meter require? My inverter can supply a 24V, 20mA digital supply will this suffice.**
A: Hi
   The unit is a great item I have got It on a three phase lathe the unit as stated requires 8-15 volts dc
I fitted a 240v ac adjustable power adapter and set t to 12 volt dc .if you go above 16 volts it can blow.
Hope this helps

**Q: Can i use a 12v 1a switch mode led psu to drive the display?**
A: Yes, 1A is enough.

**Q: Where does the sensor fit on a V twin Honda Aero motor cycle**
A: I would think the DIGITEN 4 Digital Green LED Tachometer RPM Speed Meter+Hall Proximity Switch Sensor NPN is not going to be easy to install on a motor bike.You will need to mount the magnet that's provided  to something that rotates with the crankshaftso the hall effect pick up sends 1 pulse per revolution to the rev counterthe magnet needs to pass within 1 or 2 mm from the sensorthe automotive tachometers I've seen either connect to the connection between the contact breaker (or electronic  ignition  module ) & HT coil   or use a pick up mounted to a spark plug cable

**Q: Does it come with instructions how to wire it up?**
A: Yes, it come with instructions it tell you how to wire.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked straight out the box
*by M***R on 12 March 2021*

Easy to fit. As others have mentioned the magnet is small and must be placed the correct way around. I glued it with a small dab of superglue. My maximum speed is 2000rpm so not expecting problems. At the specified 2-3mm distance it works fine with no erroneous readings. I had a 12V supply already available on the equipment and this worked ok. The settling/refresh time at reaching zero speed seems excessively long- but maybe it waits for this time to see if another pulse is coming - allowing it to read to very low speeds. Once rotating the reading is stable and refreshes regularly. For the price this is good value. Cannot comment on reliability as only just fitted but it appears robust. The application will run for several hours/day most days so will know more soon - will comment back in a few months if disappointed.

### ⭐⭐⭐⭐⭐ Excellent....it works and sensible price
*by B***E on 18 December 2018*

I’m very pleased with this...it’s been added to a metalworking lathe as attached photos. In order to keep things out of the way and clear of oil and swarf, the magnet is glued to the spinning knob at the rear of the headstock and the sensor is mounted in a wooden block underneath it, at an angle so that it’s roughly at right angles to the magnet face. The counter is also mounted at an angle in a wooden block, which allowed all the connections to be neatly inside. Both wooden blocks are held down with Velcro so that they can be removed and repositioned easily. Straightforward to fit...could be done simpler but I wanted it to be neat and out of the way. But it’s really good. I’m running mine off a 12v supply. A stronger magnet would allow the sensor to be placed further away...I did experiment but used the supplied one in the end because although I do have much stronger ones available, the supplied one did work at the required distance and it’s quite thin so doesn’t create much of a projection on the knob.I’m so pleased with this that I’ve just ordered another one as a spare! Recommended.Ps...as others have said, you need to get the magnet the right way up or it won’t work!

### ⭐⭐⭐⭐ Worked perfectly for two years
*by C***6 on 27 May 2019*

Worked perfectly for two years, but then unfortunately the display blanked.To be fair, the enviroment was not ideal as it was fitted in a boat engine room with some vibration and voltage up to the max allowed of 15v.I did check the unit was still powered OK.I’ll replace it with a similar unit, but perhaps stabilise the voltage to 12v in the hope of increasing reliability.
