Real Power Calculation on Omnimeter II UL v.3
Posted: Thu Dec 16, 2021 9:17 am
Hello EKM Support,
I am attempting to perform power consumption analysis on several products. Specifically i am looking at a 120V , two-wire, single-phase device, powering two electric motors. I am measuring the power using a Omnimeter II UL v.3.
My question is how is your reported "RMS_Watts" value calculated internally? Based off of the recorded current, voltage, and power factor my hand calculation of what expected Watts should be does not match the value reported by the meter. I've attached a screenshot of some example data.
Whether my calculations are incorrect or if there are some other variables i am not accounting for, any insight would be greatly appreciated!
Thanks,
Thomas
