Is this a mechanical or electrical tachometer?

Electrical! Easy to install and works smooth with no jumping needle! Also has pretty blue backgroud!

It's an electrical tachometer. Works great but the blue light is a bit much.

It's electrical. There's four connections that need to be made, ground (use negative side of battery), ignition, high-beams, and the negative side of the coil.

It is electronic - has a cool blue LED back light and pics up RPM pulse signal from CDI module wire or coil,,,

It is mechanical.....push buttons to enter your code, much like a turn dial on a school locker. When the correct code is pressed, the lock opens. NO digital readout or anything.

I believe it was just electric. We returned it because the cd player did not work.

No, it is a simple volt meter that uses the battery you are testing to supply the needed power. It has two scales printed on the face of the meter, one for button cells and one for all others.

I believe it is a spectrophotometer type sensor. I have sold the unit as it was not suitable for professional commercial printing work. However, I believe the tool would work well for interior design and similar applications.

This is a combination Oscilloscope and Multimeter, for that it is a bargain considering the cost. If you need industrial type for commercial use, look at fluke scope meters.

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

just markings. it is a simple, mechanical range finder. look elsewhere if you want an electronic range finder.

What do you mean by "mechanical?"Aren't they all to some extent or another?

It is analog and no batteries. I presume it is accurate. Not sure if it is ok for commercial applications.

I dont see any microchips on this or the original Siemens air flow meter.Both units appear identical by just looking at them

Sorry I haven't yet installed mine. However from what I can tell, it requires digital speedometer and tachometer wiring. It will not work with mechanical equipment.

I am sure the HP measurement is mechanical power not electrical. Mechanical power in this case would be a function of torque and rotation as opposed to electrical power which is voltage and current.

electric, but my power supply went out after 6 months. quirky unit had first replaced, refills expensive. Doesn't always work when it does it is fair.Not many out there that can polish well. I wet both pads. noisy.

Electric. Works great I love mine. Some of the comments said not to spend the extra on the upgrade unit with a timer. I am so glad I did. It makes it much more convenient.

Yes, you can check the function of a diode with any ANALOG meter. The needle should swing only one way as you reverse the leads, because a good diode only conducts (current flow) in one direction. If you switch the leads (while on a low resistance scale) the meter should not "conduct", swing up if it did when they leads were reversed.This has been a good meter for me.

It's electronic. I had two of these bikes and I had to send them both back as each one began to make knocking noises in the wheel. They cost too much to risk having them fail after their warranties ran out. Got a pedal exerciser from Amazon for around $60 and it works great.
