If the specified variance or standard deviation is exceeded, then the sample count
is reset to zero and the failed spec is displayed on the 5
th
line of the display. Line
6 of the display consists of the total measurement count, the number of samples
which have currently been taken for the valid sample set and the current variance
(ppm) and standard deviation (ppm) for the valid sample set.
When the number of samples specified has been measured and have not exceeded
the specification then the calibration routine has successfully completed and the
actual variance (ppm) and standard deviation (ppm) is displayed. If for some
reason the routine continues until the maximum retries has been reached, then the
last window of samples is used to generate the current variance (ppm) and
standard deviation (ppm) that is displayed. The values are not stored in the 6530
non-volatile memory. When the calibration is complete it will allow the user to
<save>
the values or to select another capacitor and
<Calc>
the calibration
coefficient.
