Doing what, Electrician or technician?


Cheap A$$ POS flea market meter will give you the same voltage readings a high dollar Fluke will. Electronics has narrowed the gap between cheap and expensive meters, the only real difference now is quality, durability, features.
For home use measuring AC voltages, there is no real good reason to spend over about $40 bucks for a new meter. If he is doing some sophisticated testing that requires accuracy better than a hundredth of a volt, then get a good meter.
