All about calculations
How is power factor calculated?
We calculate power factor off of real power (P) and apparent power (S). Where pf = P/S. Real power is calculated from the product of the Instantaneous Voltage and Current. Apparent power is calculated from the product of the RMS values for Voltage and Current.
AC (RMS) / DC (Mean) / Frequency values
The Channel Checker shows 4 values for each channel input:
- AC+DC (RMS)
- Geometric sum of the AC and DC values. May not match the numerical sum of the AC and DC values.
- AC (RMS)
- AC-only RMS value of the signal input.
- DC (Mean)
- DC-only value of the signal input.
- The frequency count of the signal. Firmware v4.0.5 and above calculates this based on the zero-crossing of the signal, firmware prior to v4.0.5 calculates frequency based around the mean-value of the signal.
Ratings, certifications, etc

LEED Credits for Submetering
See attached document for information LEED v4 credits that are applicable to the eGauge and metering.
Firmware Upgrade Bugs before v4.0.4 (EG4xxx)
Certain firmware versions prior to 4.0.4 have problems with firmware file uploads. On EG4xxx (Core/Pro), if firmware upload fails prior to v4.0.4, install v4.0.1 followed by v4.0.4:
1) Install v4.0.1 via file: download
2) If successful, install v4.0.4 via file upload: download
Newer firmware versions can be installed normally via online-connected download or manual file upload (latest versions available via eGuard).
