### IGBT Pulse Width Correction

see Service manual, ADJUSTMENTS

has to be carried out:

- after high tension tank replacement
- after converter replacement (1 or 2)
- after replacement of PCB kV_control EZ130
- after exchange of PCB CU if no CU Complete (for the NVRAM) backup is available
  (value is stored in CU memory) if the NVRAM has been erased or the battery is down and no backup file available

- after changing the mains voltage value (see 'Mains data')
