5.2.7 Continuous measurement control (CMC function)
The Continuous Measurement Control (CMC function) facilitates to evaluate
the current measured value instantly and definitely.
After each successful calibration the scale of the pH measuring range is
displayed in the measured value display. Here you can very clearly see
whether or not the current measured value is in the calibrated part of the
measuring range.
The following information is displayed:
The limits of the calibrated range are determined by the buffers used for cali-
bration:
1 Measuring range for which a valid calibration is available (white).
Measured values in this range are suitable for documentation.
2 Measuring range for which no valid calibration is available (shaded).
Measured values in this range are not suitable for documentation. If
necessary, 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.
