The OM-DVCV, from Omega, is a self-contained, precision instrument for recording AC current and AC voltage. The OM-DVCV can record voltage up to 600 Vac and current up to 300 Aac.
The OM-DVCV records true RMS AC current and AC voltage, it measures RMS signals up to the 21st harmonic at 60Hz. The OM-DVCV can store up to 21,672 points when recording both voltage and current. It can store up to 43,344 samples when recording only voltage or only current.
