Calibration Step 3

– Coefficient Calculations

The math to perform the coefficient calculation is complicated and will not be discussed in detail. There is a brief

overview in the next section. ZMDI will provide software (DLLs) to perform the coefficient calculation (external to

the sensor-IC system) based on auto-zero corrected values. After the coefficients are calculated, the final step is

to write them to the MTP memory of the ZSSC3036.

The Calibration Math

3.8.1.

Bridge Signal Compensation

The saturation check in the ZSSC3036 is enhanced compared with older SSCs from ZMDI. Even saturation

effects of the internal calculation steps are detected, allowing the final correction output to still be determined. It is

possible to get potentially useful signal conditioning results which have had an intermediate saturation during the

calculations

– these cases are detectable by observing the status bit[0] for each measurement result. Details

about the saturation limits and the valid ranges for values are provided in the following equations.

SOT_curve selects whether second-order equations compensate for sensor nonlinearity with a parabolic or

S-shaped curve. The parabolic compensation is recommended.
