Scaling of the measured values

In the factory setting, the measured values are scaled to 1 mg / LSB. You can set the scaling of the measured values in CoE parameter F800:1D "Presentation".

Scaling of the measured values 1:

The following options are available:

Option	Description
"Raw Values"	The measured values of all acceleration axes are output without scaling as unprocessed raw values of the accelerometers. The resolution of the raw values is not higher than the resolution of the measured values in mg. See diagram below.
"milli G (mG)" (default)	The measured values of all acceleration axes are scaled to 1 mg / LSB.
"Channel setting"	This option allows you to set the scaling of the measured values for each axis individually. Set the desired scaling in the CoE parameters 0x80n0:1A.

Description

"Raw Values"

The measured values of all acceleration axes are output without scaling as unprocessed raw values of the accelerometers.

The resolution of the raw values is not higher than the resolution of the measured values in mg. See diagram below.

"milli G (mG)"
(default)

The measured values of all acceleration axes are scaled to 1 mg / LSB.

"Channel setting"

This option allows you to set the scaling of the measured values for each axis individually. Set the desired scaling in the CoE parameters 0x80n0:1A.

Transfer function

The following diagram shows the transfer function of the box.

It can be seen that the resolution of the raw values is as high as the resolution of the measured values in mg.
