4.1.4 Input deviation correction setting
This function is used to correct the deviation caused by the thermocouple and
Thermal resistance sensor, rather than the deviation caused by the product.
The input deviation correction is mainly used when the sensor cannot be directly
connected to the measurement target. This function can be used to correct the resulting
temperature deviation.

For example, the temperature is displayed at 78 ° C,
but the actual temperature is 80 ° C.
In this case, you can set the input deviation value to
2 and the display temperature to 80 °C.
● Make sure the actual temperature detected is correcr,
otherwise it will cause a larger error.
● Most sensors have sensitivity grading, and higher
sensitivity sensors are relatively expensive. Therefore,
most sensors with medium sensitivity measure the
sensitivity difference of each sensor and then set the
input deviation value to ensure more accurate
measurement temperature.
4.1.5 Input digital filter setting
This feature allows the product to achieve high-precision temperature control. If the
PV (display value) is not accurate due to noise components, interference, or input signal
instability, the input digital filtering function can be used to achieve more precise
temperature control.
