(4) Sensor Bias(Input Bias)
Sensor Bias screen will be displayed when touching Sensor
.
Sensor Bias has two methods : OFF-set bias and Section bias.
Sensor Bias(Input Bias) corrects deviations caused by many reasons. Horizontal axis means standard
temperature or humidity and vertical axis means measured temperature or humidity. Also each value
could be changed to any value by touching number. OFF-set bias removes deviations by selecting
desired value when measured temperature or humidity value has overall deviations compared to
standard value. For example, if measured temperature is 10℃ lower than standard temperature,
touch Off-set
and change 0.00 to
. In this case, measured value will be compensated
by 10℃ Section bias is used when compensating deviations per section. In case of standard
temperature 80℃ and measured temperature 70℃, 10℃compensation of measured temperature is
necessary. This time please touch 80℃ and enter 70 in the number plate. After touching
, compensation is finished.

-100 ~ 200 ℃ and humidity value is 0 ~ 100 % R.H. If you use electronic humidity sensor
(Model # EE99), please set up input range to
- V d.c and contact resistance
(250 ℃ 1 % below) to the both of input terminals.
(3) Scale setting
In case of selecting sensor type as
, scale setting screen is not activated. That is to
say, RTD(Pt 100) is not related to scale setting. In case of
, please input proper scale
setting value. The setting range is
- V. Scale setting range of temperature
sensor setting screen – TH500 : -100 ~ 200℃, TH300 : -100 ~ 500℃ / Scale setting
range of humidity sensor setting screen : 0.0 ~ 100.0 %

•Partial bias can be selected by setting each section in accordance with its use
because partial bias aims to change the slope of section.
