(3) After you have set the calculated values to  " and  ", check
controller readout (A) and control target temperature (B).
(4) Although the input shift was carried out at two points, close to room
temperature (ambient temperature), and near to the set point, select
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 controller if applied.
In this example, we use the ES1A K 0 to 260_C specification.
YL an YH in equations 1 and 2 are set temperature lower limit YL is 0_C
and set temperature upper limit YH is 260_C. Check the temperature of
the control target.
When the room temperature X1 is 25_C, the readout on the controller Y1
is 40_C, and when the temperature near the set point X2 is 110_C, the
readout on the controller Y2 becomes 105_C.
