Step0: Align STEM mode, get STEM image.
Step1: locate beam in STEM image onto desired point.
Step2: Acquire EELS with very short collection time (sub milliseconds) to observe ZLP.
Step3: calibrate ZLP position if necessary.
Step4: Shift Beam energy to desired core-loss position
Step5: View EELS in continuous mode and slowly increase exposure time. Observe core-loss edge.
Step6: acquire EELS with conditions defined in Step5.
