Functions and
Operations
● Obtaining input
shift values (2-
point correction)
Temperature readings are taken using the E5AR/ER at any two points
and the actual temperature at the required location (the object) is
measured at the same two points.
[Preparations] 1. Set the input type based on the sensor.
2. Obtain a temperature sensor that can measure the temperature of the
object similar to that shown in Figure 1.
● Procedure for
using 2-point
correction
1. Correction will be performed of the temperature readings at two points: one
near room temperature and one near the desired SP. Measure the temperature
of the object when it is near room temperature and when it is near the SP (B),
and check the corresponding readings of the controller (A).
2. Set "Input shift 1" to the difference between the temperature of the object
(B) and the controller reading (A) when near room temperature,
and set "Input value for input shift 1" to the controller reading (A).
3.
Set "Input shift 2" to the difference between the temperature of the object (B)
and the corresponding controller reading (A) when near the SP,
and set "Input value for input shift 2" to the controller reading (A).
4. After configuring the settings, check the reading of the controller (A) and
the temperature of the object (B).
5. Correction has now been performed at two points, near room temperature
and near the SP. If you wish to improve the accuracy near the SP, establish
two more correction points above and below the SP. Figure 2 illustrates the
correction.
