Metrix » QC Errors/Warnings
Q: WARNING: "Meter inadequately tuned (CVRMSE Eng > 25.0; CVRMSE Dmd >35.0)"

A:  ASHRAE Guideline 14 says that the CVRMSE should be <25% for energy, and <35% for demand. The CVRMSE is almost the Root Mean Square of the deviations. It is roughly a measure of the average distance of the points from the fit line. Many see the CVRMSE as being more important than the R2 value.

Just as with the "R2 < .75" warning, there is no way to remedy this warning without tuning the meter properly.
