After you have configured the calculated values for
cnsl
for and
cnsh
, check/compare controller readout (A) with the control target
temperature (B).
Figure 4.14 — Temperature Input Shift Value

Although the input shift was carried out at two points, close to room
temperature (ambient temperature) and near to the set point, you may
want to consider selecting points close to each end of the sensor range
to improve accuracy across the full range of the sensor measurement
range.
Note:
Before selecting these values, check that they will not damage the
control application, if applied.
