AnalogInputSamples
Name:
AnalogInputSamples01 to AnalogInputSamples04
If Bit 15 of the corresponding SamplesAnalogInput register is 1, then this register is used cyclically to set the number
of samples for parameter calculation.
Information:
If the register is changed during an active measurement, then the current measurement is discarded
(AnalogInputToggleBit0X is not toggled). Keep an eye out for this, particularly with Enable in contin-
uous mode.

AnalogInputScale01
This register can be used to specify the scale of the four analog inputs ("AnalogInput01-04"). If the actual value is
greater than the value configured in this register, the respective register for the analog input ("AnalogInput01-04")
is limited to the positive maximum (32767).
For example, if ±128 is configured for AnalogInput04, then the 16 bits represent a value range of ±128 g or without
units if the crest factor has been calculated.
Information:
The configured scaling value is always based on a 100 mV/g sensor. Any sensor that has a different
sensor resolution must be reflected in the configuration.
