2.13 Dilution parameter
You can select the dilution of the sample in this menu.
How it functions If the sample is diluted before it reaches the TresCon, the dilution factor
can be selected. The actual concentration value is displayed.
Example The dilution is set to 1+3 (1 part test sample, with the aid of
PurCon diluted with 3 parts H2O).
The analyzer measured 1.00 mg/l NOx-N and multiplies the value with
the factor 4. 4.00 mg/l NOx-N appears on the display.
Note
The measuring range corresponding to the resolution is given in the
parameter ticket. By using a dilution device before the TresCon, the
dilution error becomes part of the total error.
