The “Current B” value is the percentage of user set current (“Current A”). From above illustration the Dual Current percentage
set to 55% and user set current (“Current A”) set to 103A, the “Current B” value is 103 x 55% = 56A. When pulsing the “Current
B” value for Peak current value is the Dual Current percentage times the peak current and for Back current the “Current B”
value is Background current times 0.85. See below pictures.
