4.4.10 Continuous measurement control (CMC function)
The continuous measurement control (CMC function) enables to
quickly and safely evaluate the current measured value at a glance.
After each successful calibration, the scale of the pH measuring range
is displayed in the measured value display. Here you can very easily
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 calibration:
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 (light
gray). 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 not in the calibrated range, the
color of the range turns dark gray.
If a measured value is outside the measuring range of pH 0 - 14,
overflow arrows are displayed at the right or left edge of the
measuring range.
