And Brymen have confirmed that recalibration after firmware update is not required. --- End quote --- When I first looked at the 786/9, I was told that swapping the IC could require the meter to need realignment. While working on the review of the 769, this came up again and they provided a little more detail, suggesting that it only effects the 789. I wonder if reprogramming the firmware for the 789 vs swapping the IC would still require realignment. Shipping takes a fair bit of time. I'm still waiting on the new 789 to arrive so we can move ahead with the review. |

As the micro likely has internal ADCs for auxillary measurements that will have individual calibration factors. EDIT: I can confirm that the micro contains a 21bit sigma-delta ADC, and I presume this is the main measurement ADC. So yes, certainly you can't just change the micro and expect zero measurement difference. |
