HI IMHO everything that measures something should be subjected to periodic calibration being it a 5-digit precision laboratory voltmeter or cheap piece of junk like ups, both can benefit from being calibrated with higher precision instrument (not only to improve measured values but also to determine the errors and repeatability of the measurement)
Hopefully the model detection will make it and at least the coarse conversion factor would be there for cyberpowers and others that need it. If calibration has no place in your config files I'll do it in my application and I can live with 21V "voltage" for 12V battery reported by it's HID Best regards, Davor On 4/11/08, Arjen de Korte <[EMAIL PROTECTED]> wrote: > [...] > > > So everybody can calibrate his own ups battery measurement > > make the polynomial fit and just enter the coefficients in > > ups.conf or just use recommended values for some models > > that are know to have systematic error > > > > what do you say? > > I don't think this is a good idea.
