Two math formulas are used to convert actual values and user-defined units: (1) the point-slope formula and
(2) the slope-intercept formula.
1. Auto Scaling by the point-slope formula
Auto Scaling by the point-slope formula can help eliminate high end and low end extremes. For example, a
temperature reading of 17 mA is already dangerously high, so there would be no need to wait for a higher
temperature reading before responding. Instead, you can cut off the values beyond 17 mA and convert it to
a proprietary level of danger, such as Level 5.
2. Auto Scaling by slope-intercept formula
Auto Scaling by the slope-intercept formula provides linear conversion between a ratio (M) and offset (D)
value. The offset (D) can be the initial value of the field device. The ratio (M) specifies the proportion by
which to enlarge or reduce the scale. It is also easy to modify the values in the database if you need to use
new ratios and offset values in the future.
