I normally use the drive panel meters for voltage and current readings, but everyone keeps asking me at work where to measure voltage and measurement with a VOM. I would check line voltage at the input but can you measure current? The line side current always seems different than the drive meter. If I measure a 480VAC drive at line input at 50 amps with a clamp current meter, it always seems to read higher at the drive for example 58 amps.
