Measurements Bias Parameters
5575
5109-5110
F
DP bias value is being added to the DP measurement producing an overall offset
adjustment.
RO
√
5576
5111 – 5112
F
SP bias, see preceding register for discussion.
RO
√
5577
5113 – 5114
F
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.
R/W
√
5578
5115 – 5116
F
Set SP to value, see preceding register for discussion.
R/W
√
5579
5117
x
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.
