10.2. Linearization (Scale setting)
10.2.1 Common case : rectangular tank 2 points
The diagram below gives an example of setting for a display level 0 to 1000 for an
input signal from 4.00 to 20.00 mA.
SCLP = 2
Point 0 :
ISC0 = 04.00 ; DSC0 = 0
Point 1 :
ISC1 = 20.00 ; DSC1 = 1000
With ISC1 = 20, DSC1 corresponds to the full scale of the sensor.
∆
Usual scaling : 2 points right lane
It's possible to invert the way of linearization in choosing
RSCL = YES. In this case, the display will be 1000 for 4.00 mA and 0
for 20.00 mA.
To display the
volume of the tank (V), if the heigh (H) is different from the full scale
of the sensor (PE), enter the following points :
SCLP = 2
Point 0 :
ISC0 = 04.00 ; DSC0 = 0
Point 1 :
ISC1 = 20.00 ; DSC1 = (PE x V) / H
