d)
Any electrical input falling outside the bounds specified by the table will be
regarded as out of bounds and under-range or over-range will be indicated
instead of the Process Variable. If a small amount of valid signal over/under
range is required, this must be built into the linearisation table.
4.2.2.14 Square Root.
When the Square root characteristic has been selected, the engineering range will still
increase from LO to HI as the electrical input is increased, but the response will be a
square root rather than Linear, see the diagram below.
The bottom 1% of the range is made to reflect equivalent linear value (times 10) to
avoid the near infinite gradient at zero. The Process Variable is set to Low engineering
range for all negative electrical inputs.
