It first requests the 100 gram weight and then the 200 gram weight before it will go to the PASS indicator. I haven't had a scale that calibrated like that before.

That sounds like the firmware is confirming the slope of the strain gage readings as well as known values. This is better for things like detecting damage to the sensors.
