Each live level (height) measurement is converted into a percentage
(0 to 100%), which is proportional to the maximum height (P014). In graph
terms, the converted percentage corresponds to an X ordinate on the X-axis.
Given the X ordinate, the Y ordinate is then calculated to determine a
percentage, related to the maximum PV (P013). The 'Y' ordinate, a
percentage, is multiplied by the value of P013 by the transmitter to determine
the final output PV.
NOTE:
• The origin (0,0) is used as the start point. It is not a parameter.
• Profile Point 10 may, or may not, occur at the height entered in P014. It is
possible the PV corresponding to this height is less than 100% of P013.
This means that P013 can be selected as any value above the maximum
to be monitored. (See Figure F-3 on page F-8).
