FILTER LEVEL
10.2.8.
It is possible to configure a pre-set filter level (this is a combination of the two sections described above).
Depending on the level, the response time will also appear, in particular:

ADVANCED
Dependent
on the
configuration
The higher the filter level the more stable (but slow) the weight measurement will be.
In the "Advanced" mode it will be possible to act on the individual filter parameters (to be used only by experts
or on the advice of Seneca personnel).
ADVANCED FILTERING
10.2.9.
These parameters can only be configured by expert personnel or at the suggestion of Seneca:
10.2.9.1.
NUMBER OF SAMPLES OF THE MOVING AVERAGE
It is the number of samples on which the moving average is calculated, the more it increases and the slower
and more stable the response of the filter is (minimum 1, maximum 100).
10.2.9.2.
ADC CHOPPING
It allows you to enable the ADC chopping feature (it decreases acquisition speed and noise and improves
ADC performance).
This mode can only be activated with the calibration with sample weight mode
.
10.2.9.3.
ADC SPEED
It is a parameter that configures the sampling rate of the ADC.
With
ADC CHOPPING DISABLED
it can be configured from 3 (maximum speed) to 255 (minimum speed).
The speed is calculated with the formula:
