Testing the Ohms of armatures.

I use the washer to "zero out" the ohms on the lowest ohm settings of the multimeter.
Once you find this number, you must subtract it from your pole reading to get the actual ohms.
Any ohm meter with 4mm banana plugs will work with the reader.
They are 22 bucks with free shipping.

Easy to use.
No more problems with reading your armatures.
It works with the armature on or off the gear plate.
