To get a good precision from the instrument, you should calibrate
it on a regular basis.
Calibrations allow to adjust :
•
ZERO of the system.
•
SLOPE of the system.
•
Both ZERO and SLOPE of the system.
The ZERO calibration is performed by the
SILKOSTAT/chemically.
In order to avoid the use of water free of SiO2, the SILKOSTAT
carries out a measurement without a colorimetric reaction.
The slope of the system is calibrated with a known concentration
of SiO
2
standard solution.
Three types of calibration are available :
•
Primary calibration.
•
Manual execution.
•
Automatic execution.
