Calibrating B+ thresholds and switching points
You can recalibrate the XR6/XR3’s high and low B+ voltage thresholds, if necessary, using the
Calibrate B+ Thresholds and Switching Points
page. You can also determine the points at which
the XR6/XR3 B+ voltage switches between levels 0 (low), 2 (medium) and 3 (high) for 3-phase XR6;
levels 0 (low) and 3 (high) for 3-phase XR3; or levels 0 through 3 for 1-phase XR6/XR3.

The transmitter is calibrated at the factory. Do not change calibration settings unless absolutely
required.
