Energy Stability of EELS

Because of the long acquisition time for the 1-D (one dimensional) or 2-D (two dimensional) scanning of the probe, spectrum fluctuation may occur owing to accelerating voltage instability and the existence of a stray magnetic field in the spectrometer.

On the other hand, lower voltage TEMs have the advantage of achieving high energy stability for EELS.
