Joseph, As you can read from previous messages, we have now found 15 ADCs with a value outside the spec 2.442V +/- 0.1%. From a total number of around 800 ADC. We do not have a table with reference values because we do not measure this voltage as standard. Only when a certain measurement function fails, we checked the reference, and then see values outside the 2.422V +/- 0.1%. We have at values between 2.450V and 2.489V. We also measured a couple of ADCs without problems and then the reference values are between 2.442V +/-0.1% Roy
