B+ Calibration
The
B+ Calibration
page (see Figure 2.85 ) displays the measured B+ levels, the B+ Limit Setpoint
(high voltage alarm level; nominally 420 V) and a calibration box. The B+ calibration value allows you
to enter a measured B+ voltage to calibrate the B+ based on an externally measured B+ level.
