A tenth? Difference in calibration between meters. When I was measuring a coil using my cheapie Harbor Freight multimeter I was getting readings that were "all over the place." I took out my good meter and got a lot more steady and sensible readings.

In the back of the meters there's a potentiometer used to calibrate it at the factory. They can miss by a hair :)
