Well, no. I though it was IN calibration because it showed a tight 12v regulated supply as 12.0x volts. But now I have to suspect that source--because I remembered where I had failed to unpack my other DMM from, and the other DMM said "He's nuts". The other DMM seems to read much closer to the SolarBoost readout, and it is the better quality of the two.
I've got to do some more looking at this, poll the usual suspects and see what seems reasonable. Ain't gonna send either one off for lab calibration though.< G >
