ALLOSUN EM127 Digital Automotive Meter Digital Multimeter RPM Dwell Angel Ignition System Test Duty Cycle Measurement 1999 Reading LCD DCV DC Resistance Measure

If you still work on older vehicles with points it's important to have when setting the dwell. It won't be much longer and you won't be able to get a dwell meter in my opinion.

To say I was skeptical is an understatement, but when I got this, it worked really well. I feel I can trust it, seems like a very nice product for the money.

I bought this mainly so I could get a dwell reading for my 4 cylinder tractor that has points and condenser.The read out didn't make any sense. Set correctly the dwell should be right about 40 degrees. I was getting negative numbers and symbols that had nothing to do with anything. Just to see I checked RPM and the readout was some ridiculous number that made no sense at all. If there was a negative star rating this would get it.

The product description says that this is supposed to come with a battery, the battery was neither in the unit or in the packaging and I had just been in town and had to drive 15 miles back to get a battery for it, I was trying to use this in the dark to work on an engine and the "Low" / "High" lights kept popping on and are so bright and blinding that I couldn't see the screen, I am going to put some white tape over them. The "Dwell" setting was giving me a reading before I even had both test leads hooked up so I have my doubts that it is even working right. The battery door is also -very- hard to remove because the rubber shell is in the way, the instructions say to remove the rubber shell but it will not come off I ended up prying the battery door off to get the battery put in. Over all I am not really happy with this device.

Easy to use and small in size.

Has all the measurements I need!

Cheap price hope it works properly.

The dwell angle was the reason meter was purchased but returned it because that was the one thing it would not read. Very disappointing.
