In the printout, the sensor evaluation is quoted as a percentage (1-100).
The finely graded sensor evaluation of the QSC function promptly calls your
attention to changes of the sensor.
Thus you can do what is necessary to restore the optimum measuring quality
(e.g. clean, calibrate or replace the sensor).

QSC function
QSC calibration The QSC function is enabled by once carrying out an additional three-point cal-
ibration with special QSC buffer solutions. It covers the measuring range of the
sensor (pH 2 to pH 11). The QSC initial calibration determines the actual con-
dition of the sensor and stores it as a reference in the sensor.
To meet the high requirements of a QSC initial calibration, the QSC initial cali-
bration should optimally be carried out with the initial commissioning of the sen-
sor.
Carry out the normal calibrations for your special measuring range with your
usual standard solutions as previously done.

Very fine grading of the sensor
evaluation (100 grades)

The reference value is individually
determined for each sensor during
the QSC initial calibration.
A theoretical reference value is used
for all sensors
Low tolerances for zero point and
slope when using QSC buffer solu-
tions
Greater tolerances for zero point
and slope when using commercial
buffer sets
Additional QSC calibration
required (with special QSC buffer
set)
No additional calibration required
