Default Testing the Tester

Using my volt/ohm meter I am measuring the resistance of a stator coil. The published accepted value 0.288 ~0.430 My meter tells me the value of the coil is 0.510 .
When I connect the black lead to the red lead (as a test) my meter reads .200 This means that the leads of my meter have .200 ohms of resistant. So using new math .510 less ambient resistance of .200 means the calculated value is .310 does this sound correct?????

Yes, but at those values, the connection between the probes and what you are trying to measure is pretty important. Use alligator clips or something like that to be sure you have a good connection.

Well it sounds right, but for measurements that critical, I would use a better meter; at least one with a zero adjust.
