Calibration Advanced
In some circumstances it may not be possible to apply inputs in which case the calibration can be entered
manually.
For example, if a sensor manufacturer provides a calibration table for a cell it may be possible to calculate
gains and offsets and enter these values into the Advanced Calibration page without having to connect the
input sensor.
Items you can change:
Number of Calibration
Points
Enter the number of points you wish to calibrate over. In its simplest form you
could select two for a linear calibration.
For more complex calibrations which include linearization select three to nine
points.
Input Points 1 – 9
(mV/V shown in this
screenshot)
Enter the input point to which the associated interpolated gain and offset
values will be applied. Note between points the gain and offset values are
linearly interpolated.
Inputs are extrapolated below point 1 and above point 9.
Gain 1 – 9
Enter the gain value for associated point
Offset 1 - 9
Enter the Offset value for associated point
Rotary limit
This is the value at which the input will move from maximum to minimum
value. This is useful for applications where the potentiometer input is endless
i.e. moves from the maximum to the minimum as it wraps round. This
parameter stops the unit reporting values outside the viable input range.
System Zero
You can set the system zero value here or set it to zero to remove the system
zero effect.
