3.19.2 Example Parameter Settings
For example, an AFM module is going to be installed with an existing 540 ADC rated
bridge. The bridge has CT's with one turn on the primary and 4,000 turns on the
secondary. A burden resistor across the CT is rated at 5 OHMS, 5 WATTS.
FOR THESE CONDITIONS, the parameters are set as follows:
