Confirming SEER with RedFish & MeasureQuick
Subscribe to our Youtube channel
The toolbox within MeasureQuick allows the user to connect tools to the software and report readings directly inside the app. In this case, Jim connects his RedFish meter and checks the wattage of the unit. After connecting the amp clamp and measuring the voltage across the contactor at the indoor unit, Jim reads the wattage in MeasureQuick and gets the power factor reading as well. He captures the reading and saves it for later.
Low power factor on an ECM is typically fine, as ECM motors pulsate. In this case, the power factor should be near unity (1) at the outdoor unit. After Jim takes his voltage and amperage readings at the outdoor unit, MeasureQuick determines that the power factor is indeed unity (1). Again, Jim captures the reading and saves it for later.
MeasureQuick takes the wattage, power factor, and BTU capacity data to calculate the EER and SEER ratings automatically. In this case, the unit is running at 13.8 SEER, which is pretty close to its actual rating.
