Calibration Data Part 2

Accidentally deleted the other post, when I tried to update the formatting.  Here's another go, this time with a 7 day old sensor, transitioning to a 0 day old sensor :).  Interesting here to see how the Intercept doesn't change.  Slope was 906 before recalibration, SAME intercept.  This sensor has had other intercept values, most recently 27626.

With two more calibration data points, slope is at 820, intercept continues to be unchanged.

  1. Hi Don. that record has 2 sub-records in it, It also has the bootstrap intercept value of 30000. I think you'd find the previous cal record has intercept of 0. Otherwise the receiver would need some way of identifying the sensor in order to tell the difference between a new sensor and a restarted sensor. I don't believe it can tell the difference, so just boot-straps again.

  3. Hi,
    Unfortunately I can't help but I reeeeeeally appreciate what you're doing.
    The only way I could help you is providing the electronics of an animas vibe. Would it be in any way useful? It should be working and I have pictures I took during dismounting.
    Regards
