So for example with the value 3 we get an ADC speed of:
𝑓𝑓
𝐴𝐴𝐴𝐴𝐴𝐴
[
𝐻𝐻𝐻𝐻
] =
4096
3 = 1365
𝐻𝐻𝐻𝐻
With
ADC CHOPPING ENABLED
it can be configured from 13 (maximum speed) to 255 (minimum speed).
The speed is calculated with the formula:
𝑓𝑓
𝐴𝐴𝐴𝐴𝐴𝐴

[

10.2.9.4.
NOISE VARIATION IN ADC POINTS
It represents the variation in ADC points due to noise alone (represents the measurement uncertainty due to
noise) or how much we expect it to vary (the unit of measurement is in rough ADC points).
10.2.9.5.
FILTER RESPONSE SPEED
It represents a parameter related to the filter response speed, it can vary from 0.001 (slowest response) to 1
(fastest response). Represents the variance of the process.
NET WEIGHING RESOLUTION
10.2.10.
It is the resolution with which the net weight value is represented.
10.2.10.1.
MAXIMUM RESOLUTION
It will represent the net weight with the highest possible resolution
10.2.10.1.
MANUAL
It will represent the net weight with the manual resolution set (in engineering units).
For example, by setting 0.1 Kg you will get that the net weight can only vary by multiples of 100g.
10.2.10.2.
AUTOMATIC RESOLUTION
It will represent the net weight with a calculated resolution of about 11000 points. Unlike Maximum or Manual
resolution, this setting limits also the ADC value and therefore affects all measurements.
