Select Start, make sure that the hardware setup is correct, and select Yes.
After approximately 1 minute, you are asked to confirm the peak power value output from the amplifier. The peak power should be within the limits specified in 8 kW 3.0T MNS Amplifier Calibration. If the power read from the power meter is within these limits, click Yes. Otherwise, click No and recheck calibration of the RF amplifier.
The window shows the current step in progress, and indicates Pass/Fail when complete.
