Resolution and Range

Selecting Enable/Disable Cyclic Autocalibration (Word 6, Bit 0)

Configuration word 6, bit 0 allows you to configure the module to
perform an autocalibration cycle of all enabled channels once every 5
minutes. Cyclic calibration functions to reduce offset and gain drift errors
due to temperature changes within the module. Setting this bit to 1
disables cyclic calibration, the default (0) enables the autocalibration
function. See Effects of Autocalibration on Accuracy on page 4-33.
For systems that allow modifying the state of this bit, you
NOTE
can program the autocalibration cycle to occur whenever
you desire via the ladder program, by cycling the bit from
0 to 1.
This section provides tables showing effective resolution and range for all
possible input data types at each filter frequency. Look up your required
resolution, range, and input type in the tables. Choose the frequency that
most closely matches your requirements.
