Sedecal generators are factory calibrated, but drift occurs over time due to temperature cycles. The service manual provides the "golden sequence" for calibration using a non-invasive kV meter (e.g., Radcal or Fluke):
While this helps, it is no substitute for the real , which explains how to interpret the IGBT temperature (should be < 85°C) and bus voltage (should be 340V DC for 230V mains).
