Measurements Bias Parameters
DP bias value is being added to the DP measurement producing an overall offset
adjustment.
SP bias, see preceding register for discussion.
Set DP to a value, units are same as the DP measurement.
DP bias = value – current measurement.
This results in the reported value in register 401-402 to be the value.
Set SP to value, see preceding register for discussion.
Reset DP Bias, sets the bias value to zero, effectively removing any effects of bias
on DP measurement.
This is an action register and the data value has no meaning.
Reset SP Bias, sets the bias value to zero, see preceding register.
