Dolphin Ampmasters
Hey Darren.
Dont know what the manufacturer told you about measuring across a pole - IME it has always been on a power lead at the motor.
As far as the 2.2amps goes, if this is a good number the motor should have tripped a long time ago. Makes me pretty confidant its somehow not a good number (no offence to yourself or your equipment). I doubt that the "loss" is due to the cord or wiring - pretty low draw. It really sounds like its operating properly. Did you try the Fluke inline? Or maybe try it at the cord end if you dont want to mess with the motor? Never had much luck with any ancillary accessories for low amp measurement on those meters. Most times only used a RMS meter for VFD's as they tended to screw me up more often than not for everyday use.
Maybe find someone with a regular clamp-on? (meter that is [img]smile.gif[/img]
Or don't sweat it. Pumps sounds like its running fine - have a beer.
