85 10 Advanced Meter Features Multipoint Calibration Curve Feature The Orion Dual Star meter utilizes a point-to-point scheme for multipoint calibrations in both pH and concentration modes. In this technique, straight line segments are drawn between each successive pair of calibration points. Separate slope and Eo values are calculated using the adjacent pair of data points. For example, in a five point calibration, four slopes and five Eo values are calculated to correspond to the four line segments that connect the data. Concentration or pH values for samples are calculated according to the segment that their potential values fall into. Those above or below the range of calibration are calculated by extrapolation from the top or bottom most segment. The displayed slope is an average slope of the separate segments. The slope may be outside the range normally expected for an electrode. For example, if the slope of one segment is low, then the average will be lower than theoretical, even though the response may be Nernstian over most of the range. The following figure is an example of a typical calibration curve using this method.
