Sample preparation of the calibration solutions:
In the case of multipoint calibrations, the calibration takes place outside the process. For
this, a sample is taken from the process and prepared accordingly.
1.
A0020482
Take a sample from the process (e.g.10 l (2.6 gal) bucket).
2.
A0035855
Wait until the sludge components have settled.
3.
A0035856
Siphon off the excess water (if possible) in order to increase the concentration of the
sample.
4. Stir the sample to make it more homogeneous.
5.
A0020485
Remove a portion of the sample for laboratory analysis.
6.
A0020486
Transfer a defined amount of the sample (e.g.2 l (0.5 gal)) to the calibration vessel
(bucket).
7. Continue stirring the sample to maintain homogeneity.
