HAADF detector doesn't give a signal
Eventhough the HAADF detector is inserted properly, it sometimes doesn't give a signal. This is typically the case at the beginning of the session, when the detector is used for the first time. If this is the case, try the following:
- Go to the "STEM Detector (User)" control panel
- Open the flapout
- Un-check "HAADF"
- Check "HAADF"
- Try imaging again. The detector should give a signal.
