Calibration Advanced - Mantracourt T24-ANTA User Manual

Calibration Advanced

In some circumstances it may not be possible to apply inputs in which case the calibration can be entered
manually.
Items you can change:
Number of Calibration Points
Input Points 1 – 9
Gain 1 - 9
Offset 1 - 9
System Zero
Description of Linearisation Calculations
The input value is looked up in a table of points which is dependent on what the user has selected, starting from
the bottom of the table. When a point is found to which the input is less than then this point and the previous
point are used to extrapolate a gain and offset from. This leads to a resultant gain and offset which is applied to
the mV/V values as follows.
Value = (input * Resultant Gain) – Resultant Offset.

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.
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.
Enter the gain value for associated point
Enter the Offset value for associated point
You can set the system zero value here or set it to zero to remove the system
zero effect.
