I don't buy the 'requiring recal' excuse either.
The meter has three sources of autocalibration delay. The first is an enforced delay on changing mode or range, which depends on the switch that was performed. When this delay is active, the display is blanked and the autocalibration routine does not run. The second is a sample averager, which is 8 samples for OHMS range and 16 for every other. This average value controls the screen display, and the current sample controls the bargraph. The same calibration factors are applied to both numbers. The third is a rolling average applied to the screen display, which depends on the mode and range as well. This should not be a factor, as the average resets on overrange or a large measurement delta.
The autorange is performed on the final displayed screen number that you see, after all three sources have been factored in. There is little to no software or calibration reason they couldn't shorten the delay during autoranging (which is what I think the v1.04 firmware does) or use the bargraph value initially. The calibration factor applied is the same for both measurements.
I've made a patch which removes that mode/range change delay while autoranging, but I can't test it without a meter. I'm now wondering if anybody would be willing to sell me their meter for testing purposes?
