Complete Calibration Procedure
4. Gain calibration with XPS. A calibration check for the gain of the 1500V and
3500V modules see section 7.7 on page 64
5. and in section 8.2.2 , "Check Peak Position" on page 66, verify that the peak po-
sition in an XPS fit to the modifications of offset and gain performed in the se-
lected range.

7.2 Recalibrate the DAC Precision
Note: the power supply needs time to warm up. A self calibration procedure for the
DACs is run every time the power is switched on. You should restart the DAC calibration
procedure after a warm up (5-15min, switch off/on or use the field “Recalibrate DAC
Precision” in the menu ’Analyzer/Settings’ figure 26, page 58). Temperature stability as
