    It depends on what you want to do with the information. The readings will give you an idea of how good/bad the insulation on the windings actually is. On small systems it may give the customer some extra time on a compressor by giving clues that there might be moisture or acid in a system. There is plenty of information on the "Fluke" website for this type of testing instrument.

    There are many different meters that can read megohms, the more voltage that they put on the system, the more thay cost. I don't believe that you need a crazy expensive unit if your main line of work is in residential.
