How to calibrate HVC analog input Fbox?
FAQ #100538
Analog input Fboxes with individual callibration have the following parameters; Mode, range and offset to be adjusted. The following formula helps to adjust those paramters
In order to use this formula the paramter mode has to be kept to default value: R-0
Range = (Ymax - Ymin) . Imax Y = Fbox output value
(Imax - Imin) I = Analog carte input value (mA, mV)
Offset = Ymax - Range
Example: the sensor gives 4...20 mA and we want to display a value from 0...500 m3 using a PCD4.W300 card!
Range = (500- 0) . 20 mA = 625
(20mA -4 mA)
Offset = 500 - 625 = - 125
