The routine procedure to shut down the instrument is described below.

CONSOLE switches ON.
2 Place an analysis sample for blank analysis on the sample plate of the spark
stand and prevent air or debris from entering into the emission chamber.

When analysis is not performed for a long time, for example at night,
display a window other than the analysis window on the data
processing software and then turn off the monitor.
