Calibrating the pH probe
During calibration, metering is reduced to the set basic capacity. The standard signal of the output
(measured value/correction value) is frozen. The rounded-off, whole number measured value or the last
buffer value is suggested as the buffer value; this value is adjustable. On completion of calibration, all error
checks which refer to the measured value are restarted. The amount is specified at slope.
