If the sampling process has been completed without any prob-
lem, push the .
√ . button to save the sample in the table and
the measurement continues.
The process previously described must be repeated for each ad-
ditional sample.
The assumed moisture of the samples should be distributed over
the entire measuring range and the moisture should not vary too
much during each sampling step.
The measuring system has to operate at a normal conveyor belt
throughput and the usual material under actual operating condi-
tions.
The minimum number of samples required is dependent on the
selected calibration modes. If the sample size is too small, an er-
ror message is displayed after you have attempted to run a cali-
bration.
Approximately six samples suffice for a rough calculation of the
calibration coefficients, provided the moisture differs by at least
5%. At least 15 samples are required for a fine calibration.
Do not take the samples before the product has passed the
measuring point! The measurement would be disturbed each
time a gap is detected. See the following illustration.
