Ordered two, -- Upgrade

The first came without the plug and wire connecting the block to the sensor, but due to health reasons I didn't realize this until after the return period. I have ordered a second one. It arrived full but refuses to read the RPM. The documentation and notes on the website say it runs on 9V and in fact recommend using a 9V battery for testing. However, in the depths of the limited documentation it says that you should read 12V on one of the wires. I have ordered a 12v power adapter and will be…

Exactly as described, buy with confidence.

Short test report without bullshit. I bought 2 of these and will buy more if needed. Set it up and use it according to the instructions to set up an easy-to-use tachometer. I've used a 9 volt battery with no problems, but will be using a wall wart for a more permanent mount. Attach the magnet with tape or glue. Otherwise, you deserve to be hit in the forehead by a high-speed object (yes, I failed that IQ test myself). Mark the polarity of the magnet with a colored marker and mount it correctly.

Pros
  • Super for me
Cons
  • No instructions

Tachometer

I bought this for my Craftsman lathe. The headstock speed chart is so faded I can't read it and I can't find a chart with the same belt arrangement as mine. I used the stopper pin hole on the headstock housing as a retainer after making the pin that replaced the pin. The entire installation took a few hours and all I bought was a couple of set screws and allen screws. I also bought a Revain 9 volt battery adapter canister with a switch to power it. The readings are housed in a plastic container
