Re: resistors in series

2009-10-06 by Ehud Tamir

I suggest that you check the batteries in your DVM, I've seen more than once that bad batteries, or battery if it's 9V, will create unreliable and wrong readings.
Also, most of DVM's will measure up tp 20Mohms, and anything above would read as OL (overload - overrange).
If you measure the resistors individally and get the right values, then the total is the sum - in this case as you pointed 22M.

Hello. My point is that if you touch the probes with your fingers, the
value will be too low, and not as in your case, too high, so that's
not likely to be your problem. Still, I wanted to mention it in case
it might be relevant.
As for your actual problem, I'm chiming in with Loscha, guessing that
your problem is that the meter has a problem measuring high resistance
values.
