Filed: 1995-01-18
Abstract: PURPOSE: To instantaneously judge whether an indicated value is stabilized or not at calibration, by providing a vertical axis of a trend graph screen with a scale over zero and span values, and performing calibration-operation with a measuring instrument by observing the scale on the graph screen. CONSTITUTION: With a graphic operation panel, a trend graph screen displaying a graph which shows hourly transition of a measurement value when calibrating a water quality meter is created, and for the measurement range of a vertical axis showing the measurement value, scale is graduated up to over zero point and span values so that a value is adjusted while confirming near zero point and span value. And when, for example, reference solution calibration of turbidity is performed with a 'turbidity' trend graph screen, water quality (turbidity) of sample water is measured up to an A point.  When turbidity reference solution (for example, 4 degrees) is made to flow from the A point, the water quality of the reference solution is measured and the detected value is displayed in order on the screen, and when stabilized at a B point, the measured display value is judged whether it corresponds to the turbidity of the reference solution (4 degrees) or not, and if inconsistency exists, an indicated value is adjusted with a water quality measuring instrument converter while observing the screen.
