Region reads the position of the marker and inserts values into the fields. If the marker is in an ROI, the limits of the ROI are used. If the marker is not in an ROI: for calibrated spectra, the center channel is the marker channel and the width is 3 times the FWHM at this energy; and for uncalibrated spectra, the region is centered on the peak located within two

channels of the marker and as wide as the peak. Now click on the appropriate Enabled checkbox to turn the stabilizer on. Until changed in this dialog, the stabilizer will stay enabled even if the power is turned off. When the stabilizer is enabled, the Center Channel and Width cannot be changed.
High Voltage
Figure 82 shows the High Voltage tab, which allows you to turn the
HV on or off; set and monitor the voltage; select the HV Source and
Shutdown mode; and indicate the detector type; and Polarity. Note that if the detector is attached via the rear-panel DIM connector, some of these options may be disabled or auto-selected. For example, the detector polarity is determined by the SMART-1 or DIM module.
The Source is Internal for conventional, non-DIM detectors;
