Calibration of the device is monitored online with an analysis of the measur-
ing signal and it is shown in the graph
immission estimated channel
deviation – trend 40h
. If the calibration starts to drift, the curve of the
individual points between the two red horizontal lines drops sharply. The
points are the result of a half-hour measurement.
Error message
If the average deviation over the course of 40 hours is greater than 3.5 raw
data channels, an error is triggered. When this happens, the device has to
be verified with the MonoDust 1500; refer to the section "
.”
Individual points can lie outside of the limits. This can happen and is not a
cause for concern. Calibration is fine in this case, too.
