Intelligent

reproducibility and

plausibility check

(IRPC)

With the intelligent reproducibility and plausibility check (IRCP) a multiple 
measurement is carried out, evaluated and, by eliminating the outliers, the 
plausible measured value is indicated on the display.
The intelligent reproducibility and plausibility check (IRPC) is active with all 
measurements. It is displayed in the upper status line [IRPC].

Calibration

When to calibrate?



Routinely within the framework of the company quality assurance



When the calibration interval has expired



With a temperature change

Preparing the

calibration

For quick and easy measuring we recommend that you use marked cells with 
the calibration standards (see P

REPARING

THE

CELL

, page 9). 

If your cells are not marked you can determine the suitable position of the 
individual cells in the cell shaft while measuring.
Perform the following preparatory activities when you want to calibrate:

The measured value is automatically output to the inter-
faces (= AutoPrint).

8 Repeat the steps 2 to 8 for further samples.
