To select the Sensitivity Calibration Temperature and initiate the Sensitivity Calibration
procedure, press the
Calibration, the System Variable Heat Type must be set to ABSOLUTE and the
Heat Temperature must be set to +50°C (+122°F). See Appendix D.4. This
Heat Temperature must be achieved in Recovery Mode (see Section 3.10.6).
This procedure cools the mirror from an elevated temperature and records the mirror
temperature against the signal level. While the sensitivity calibration is in process, the
results taken are displayed as and when they are sampled. The calibration procedure
can be exited at any time by pressing the
