[QUOTE="Rob Timmerman, post: 139998, member: 172"] Re: Generator / motion labs conflicting stories... Help! Unless the generator has an inverter output (unlikely), the output frequency will be a function of the generator RPM. So if the generator speed isn't fluctuating, neither is the frequency. What have you been using for loads? Last I checked, the Motion Labs meters weren't reliable under about 10A, and it's quite possible that the frequency measurement is being confused by distortion on the waveform (THD from power supplies). Any chance you can test with something "well behaved" as your load, such as a filament lamps (PARs, work lights, whatever)? [/QUOTE]
