Well built and easy to use
I am impressed with this tachometer. It has simple instructions, works both mechanically and optically and comes with everything you need to use it. Mine came with the contact attachment installed and there were no instructions for removing it. There are two small Phillips head screws which you remove and then two small plastic clips need to be flexed to remove the contact attachment. I found that the screws were not necessary to hold the attachment in place when I was doing measurements, although it is probably a good idea to have the screws in there.I first tried measuring the speed of a Dremel. I used the concave rubber attachment with a convex grinding tool. It was a little bit awkward to hold the dremel tight to the tach but I could manage to take measurements. The tach measures as long as you hold the test button and it keeps track of maximum, minimum measured rpm. I started at the lowest speed which is around 5,000 rpm and them went all the way to the maximum which is around 30,000 rpm. This speed is too high for the tach and it displays HI. It did get a little warm too. By adjusting the speed I got a reading close to the maximum of the tach, which is 19,999 rpm.Next I tried using the optical, non-contact method. I attached a small, 1/2 inch piece of the supplied reflective tape to a polisher. I changed the measuring mode to P, photo and took some measurements. There is a laser in the tach and when pointed at the reflective tape it measures the rpm. It worked great at both low speeds, 300 rpm and high speed, 3,000 rpm. I was a little worried about the tape flying off but it stayed put. Now I know what rpm the numbers on the polisher mean. I plan to use this on my outboard for setting the idle rpm by putting some reflective tape on the flywheel.

Not accurate
This unit is very far off on calibration and no way to correct it. at 50fpm it reads 43fpm. at 300fpm it reads 250fpm

happy
happy with transaction. received what I wanted

You must be physically touching the shaft
You must have the exact shaft size adapter on the unit that matches perfectly to the device being measured.

Not accurate
It was way off in accuracy. Very disappointing.
