4.4. Absolute and Linearity Ranges of Parameters
The analyzer provides specified accuracy within its linearity range. Beyond this
linearity range, the instrument can display results but accuracy is impaired.
If a value is over the maximum range of guaranteed linearity, the instrument cannot
measure it and the result will be marked with an E (Error) flag.
To measure a sample, whose parameters exceed the maximum value indicated in
the table below, pre-dilution is recommended. See section 5.2.7 of this manual.
Linearity ranges of primary parameters in normal measuring mode:
