3. To get the correct quantity indication you require a list of points which shows the connection be tween measure current and associated quantity inside of the tank The curve fitting software of the D122 XS interpolates the curve between these points on your choice in a linear or a square way The linear interpolation generates imaginary straight lines between the selected points A value on this line will be calculated on base of his distance to the previ ous selected point This kind of interpolation requires 17 points to scale 4 up to 20 mA On the other hand the square interpolation needs a list of 33 points but it ap proximates the original curve much better than the linear one so the error be tween the original curve and the interpolated curve is much smaller To put in the list of selected point enter the extended scale menu The device displays the measure current and you have to enter the associated display value See also flow diagram in Figure 13 M Squareroct fitting To program a squareroot function e g to display the flow through a aperture a special squareroot fitting feature is available For this option it is not necessary to enter a list of points but just a start and a end value in previous example associated flow by 4 and by 20mA measure current The de vice calculates automatically the selected points for interpolation Be prepared this procedure will take some time See also flow diagram in Fig
