SENSORS SETTING
a)
When reselect sensors, the sensor curve will be transferred into the standard value. For example, if
temperature sensor is SGH (120°C resistor type), its sensor curve is SGH (120°C resistor type); if
select the SGD (120°C resistor type), the temperature sensor curve is SGD curve.
b)
When there is difference between standard sensor curves and using sensor, user can adjust it in
“curve type” and input target curvilinear coordinate.
c)
When input the sensor curve, X value (resistor) must be input from small to large, otherwise,
mistake occurs.
d)
The headmost or backmost values in the vertical coordinates can be set as same as below.
e)
For current type sensor, sensor curve is linear, and it only needs to set the coordinate of two points.
