6 CALIBRATION OF X-RAY TUBE MA MEASUREMENT
The objective is to determine the scale factor F/mA between the X-ray tube mA measurement input to
the software and the real X-ray tube mA value.
The default parameter value is F/mA = +1.000E+3 (1000) Hz/mA
CAUTION
DO NOT touch potentiometer P1 on generator kV/mA board 701-PL1 at any point in this
