The following information is displayed:
The limits of the calibrated range are determined by the buffers used for cali-
bration:
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 (dark
gray). Measured values in this range are not suitable for documenta-
tion. Calibrate the meter with buffers covering this measuring range.
If the current measured value is outside the calibrated range, this area
is displayed in a darker gray.
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
