    3. Biomed test cable PN: BTK-G400. Where applicable the equipment must have a recognised calibration certificate. *The G400 has RF output modalities that are very difficult for most electro- surgical analysers to measure. The Gyrus ACMI’s technical authority has stated that testing the continuous wave and blended output modalities of the generator are sufficient to confirm full equipment functionality.

    The reader is referred to the operator manual. Generator Internal description The G400 generator casework is comprised of the front fascia, rear panel, top and bottom panels, side extrusions and isolation board. The isolation board carries most of the Printed Circuit Boards (PCBs): Power Supply Unit (PSU), Plasmakinetic (PKRF) and the Auxiliary PCB.
