The orientation value can be quite inaccurate and should not be used
as a measure value!
Explanation
Measuring range undercut.
Remedy: Use a test with a lower
measuring range
Measuring range exceeded.
Remedy: Use a test with a high-
er measuring range or dilute the
sample
This value serves as a refer-
ence point for the selection of a
suitable test or dilution ratio.
If the measurement signal can-
not be evaluated (intensity too
high or too low), four bars ap-
pear ("----").
