are you using any extention cords? if so remove them and try it again.
you might be ok, that would be assuming your "meter" is accurate. you may want to double check it with a quality and accurate voltmeter.
my trailer, a '92, has a built in cut off on the compressor that will not engage below 109 volts. it also turns a red warning light on when this happens.
it is a good thing you are paying attention to this, low voltage and high current are very hard on ac units.
