The limits of the calibrated range are determined by the buffers used for cali-

QSC function (sensor quality control)
General information
on the QSC function
The QSC function (Quality Sensor Control) is a new sensor evaluation for dig-
ital 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.
1 Currently measured pH value (needle)
2 Marking lines for all nominal buffer values used with the last valid cali-
bration
3 Measuring range for which a valid calibration is available. Measured
values in this range are suitable for documentation.
4 Measuring range for which no valid calibration is available (shaded).
Measured values in this range are not suitable for documentation.
Calibrate the meter with buffers covering this measuring range.
If the current measured value is outside the calibrated range, this
area is shaded stronger.
If a measured value is outside the measuring range pH 0 - 14, over-
flow arrows are displayed at the left or right edge of the measuring
range.
Lower limit:
Buffer with lowest pH value - 2 pH units
Upper limit:
Buffer with highest pH value + 2 pH units
