If only the preset kVp is displayed by the unit when used in the AEC mode, is it necessary for a "preset" indication of mA and/or mAs to be indicated prior to the exposure?

Policy Guidance Help System logo

Any technique factor that is set prior to exposure in the AEC mode must be indicated. However, the indication need not be by digital display or dial. With units where the kVp is the only factor under direct control of the operator, the corresponding preset mA or mAs may be set automatically by the unit and may not be normally visible on the control panel. However, these corresponding values should be available from the manufacturer, if standard for the model, or from the installer, if they can be set to meet the needs of the facility. If these values are given on a label attached to the control panel or on the technique chart, the unit will be in compliance with this requirement.
