(12) Input correction [ CH In Bias ]
This function is to compensate an accidental error occurring by TC,
RTD or analog input excluding product allowable error.
If sensor is not able to connect with the position of additional measuring
object, this function is to be compensated through calculation of
the temperature deviation value between the temperature of sensor
connected position and the measuring object temp.
If applying input correction after measuring accidental error value for
each sensor, it is able to measure temperature more precisely.
When using input bias function, accidental error value should be
measured and if measured accidental error value is not precise, it will
be larger.
Each channel is able to set for input bias. (CH1 In Bias, CH2 In Bias)
In case of TC or RTD, if temp. unit conversion
℃ ↔ ℉ or input type
change, correction value will be initialized to 0. If actual temperature
is 80 ℃ , but display indicates 78 ℃ , input correction value [CH Input
Bias] should be set ‘2’ for indicating 80
℃
.
● Setting range: -999 to 999
In case of TC or RTD input, correction value range is as follows
Temperature sensor range: (-200 to 1350), In Bias: -999 to 999
Temperature sensor range: (-199.9 to 999.9),
In Bias: -99.9 to 99.9
In case of analog input, bias value according to the decimal point of
scale point is as following:
Sc Point: 0 In Bias: -999 to 999
Sc Point: 0.0 In Bias: -99.9 to 99.9
Sc Point: 0.00 In Bias: -9.99 to 9.99
Sc Point: 0.000 In Bias: -0.999 to 0.999
● Factory default: 0000 (unit: Digit)
