Resistance Measurement U1731C

Hi there,

Similar to my other post, I also have an Agilent U1731C LCR meter which I want to use to measure the winding resistance of a permanent magnet generator.  I've already checked the resistance using another clamp meter and know it is ~5.4ohm.

When I measure it with the U1731C (on resistance mode) the value of resistance seems to depend upon the measurement frequency (and is always greater than the actual resistance).  Furthermore, when I move the generator to a new static position (thereby changing the magnetic field) the resistance value also changes.

What am I doing wrong?
