Span Error. Span error results when the instrument does not indicate full scale correctly even if the zero is correct. This is generally considered to be a linear error that increases as the value measured increases from zero. A span error is shown in Figure 3–3. Figure 3–2 Examples of zero errors. book Page 43 Monday, May 22, 2006 4:57 PM CALIBRATION CURVES 43 Figure 3–3 Examples of span error. Figure 3–4 Examples of zero and span error. Generally, both types of error will exist in preliminary calibrations.
