Notes

Filtering: the time constant value can vary 10% of its nominal value. The maximum deviation of the time constant value is equal

to the sampling rate. Ex: selecting the constant time equal to 1 s, the maximum time for the current value with filter to have 63%

of the input value is: 1 s * 110% + 60 ms = 1.16 s. The "Disabled" option is available as of version 1.11 of the MT8200.

Counting: the scale limit may be modified by software, the maximum value is 30000.

Scale clearance: defines the percentage over limit scale that can be read by analog inputs. This characteristic can be used to

compensate possible calibration errors of a used sensor.
