4.6.10 QSC function (sensor quality control)
General information
on the QSC function
The QSC function (Quality Sensor Control) is a new sensor evaluation
for digital IDS sensors. It evaluates the condition of an IDS pH sensor
individually and with a very fine grading.
On the display, the QSC color scale (from green to yellow) indicates the
current sensor evaluation by means of a pointer.
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).

Info
QSC color scale
The double arrow on
the color scale indi-
cates the current sen-
sor evaluation.
With QSC function
Without QSC function (sensor
symbol)
Very fine grading of the sensor
evaluation (100 grades)
Rough grading of the sensor
evaluation (4 grades)
The reference value is individu-
ally determined for each sensor
during the QSC initial calibra-
tion.
A theoretical reference value is
used for all sensors
Low tolerances for zero point
and slope when using QSC buf-
fer solutions
Greater tolerances for zero point
and slope when using commer-
cial buffer sets
Additional QSC calibration
required (with special QSC buf-
fer set)
No additional calibration required
