what is the ratio for this tachometer?
325009
Being electronically operated rather than by cable, it has no ratio. Mine arrived broken though, and without instructions for wiring. beware of cheap-o ones like this.

Hi there, I'm afraid I was never able to get this tach working. There were a few references on how to hook it up on the internet, however, I was never able to do so successfully...

It's electronic, so there really isn't a ratio. It works off the primary (input) side of the ignition coil. My bike has two coils because it's a 4-cyl, but I could still use it because of how my ignition works. Google it because some people have trouble getting it working. Probably because like me they didn't get instructions.

This electronic tachometer may be set to read variable impulses to produce an accurate readout of RPM's.

No I can not tell you the ratio. The tach did not work for me:-( was disappointed in the product but it was cheaper that sending it back. Would recommend buying something else.

I called Design Technology who manufactures the tiny tach after receiving my tiny tach and they instructed me with my setup. It was quite simple and not complicated at all. They should be able to tell you if it will work with your setup. Their number is 630-920-1300......I am very happy with my purchase as i can monitor my engine rpm in real time.

One should refer to the technical specs from the manufacturer. I do not remember.

boy thats a good one my calipers say its close to 12.7mm but my scale ruler says 12mm sorry best answer i can give

I figured it out. page 24 in my manual under TAS setup. let me know if you have any questions.

7 - 100, according to the information in the product description. I have only used mine for metric measurements.

i dont know.just hook an ammeter in series with it and a battery and you'll find out

The gauge set I bought had speedo, tach, fuel, volts, oil pressure and temp. Speedo only registers 65. Wish it was 85.

Since it is variable speed it depends where you set the dial. At the lowest setting I estimate it around 500 rpm at the highest my guess is 3000. This is a very good tool for precise drilling which it what I use it for. I highly recommend it.

I'm not sure of the guage, but it's not wimpy at all. I was nicely surprised when I got mine on how study it is.

Yes, I used this tachometer on a carbureted car with coils works just fine shift light comes on around 6000 rpm. Hope you enjoy. Great buy for the price. Looks race ready.

I couldn't say either way. I can suggest picking up a cheap digital caliper. They're easy to use and that will give you a good measurement. Also they tend to come in handy pretty often. Otherwise i would contact the manufacturer they would probably be able to tell you a definitive answer. Also i would confirm the voltage with them to be sure before you damage anything.

Depends on what RPM your running it at. In general it's very quite 8/9 depending on what your scale is. At low RPM which us most of the time, you won't know it's on.

Here is some info from CNCZONE which I found when researching (The answer to your question is .1" per revolution): "BTW, the silver scale is calibrated with 100 dial markings per revolution (and the leadscrew appears to have 10 threads per inch, therefore each mark is apparently equivalent to .001"). However I'm not sure that I understand the reasoning behind (and usage of) the markings on the fixed scale - it doesn't seem to be acting as a vernier readout, but maybe I'm simply confused -"

TO SET THE TACHOMETER (SPARK PLUG FIRING REVOLUTION):Press and hold the S1 button for 4 seconds. The LCD will display 01 (spark plug fires twice per revolution),02 (once per revolution), 03 (every other revolution), 04 (hour only, will not display RPM).Once you find your desired spark plug firing pattern, release the S1 button.The LCD will blink for 8 to 10 seconds and return to total hour meter mode.The default for the standard model is 02 (once per revolution).

Do not know for sure, however there are two settings for torque. It would seem reasonable that these could be the two values
