graham is correct. you should use a megger for insulation integrity but if you are going to check winding resistance you will need a milli-ohm meter. most windings that use wye-delta starters are going to have ohm readings in the 0.001 to 0.0001 ohm range. most meters will not come anywhere close to this range and if they do it is probably not accurate enough to bother checking. i use a feildpiece milli-ohm attachment for my fluke.
