12. Quality control
The instrument performs a self‑calibration whenever it is turned on. Therefore, in general, the
instrument does not need to be calibrated. To check instrument performance, we recommend
to run multiple standard measurements with known concentrations within the tests range.
If such results are not within the test's confidence interval, (see Chapter 13.3 "Confidence
interval") please contact your distributor or MACHEREY‑NAGEL directly (see Chapter 20
"Manufacturer information").
For additional quality control assessments, you can also use the instrument's check mode and
special control strips (see Chapter 15.3 "How to run a control strip measurement").
