Dears
Recently ,i found some issues when i test
1、The capacitance value is different every time after learning completed，（Cycling test， start learning after ex-learning completed ）
2、The capacitance value goes variation suddenly than before.（See Pic）
Q1：
To 1st issue: Whether the capacitance value after learning that we get would be difference or not, Are there some things change the calculated value ?
To 2nd issue: What will cause this learning error ?
Q2:
1、How to verify the learning value is the best result to us
2、How about the capacitance value tolerances，+？~ -？.
So appreciated ,and looking forward to your response
