𝑆𝑙𝑜𝑝𝑒 =
0 − 𝑍𝑒𝑟𝑜 𝑉𝑎𝑙𝑢𝑒
819 − 0
𝑍𝑒𝑟𝑜 𝑉𝑎𝑙𝑢𝑒 = −𝑆𝑙𝑜𝑝𝑒 𝑥 819 = −2.5
We can repeat this same example using an Enriched Value in degrees Fahrenheit instead of degrees Celsius. The
register value ranges from 819 to 4095, corresponding to a temperature range of 32 to 50F.
Now the calculations are as follows:
𝑆𝑙𝑜𝑝𝑒 =
50 − 32
4095 − 819
= 0.00549
The Scaling factor is the inverse of this. It can also be thought of as the “One in X” gradient of the graph.
