4.2.6 Setting an Observation Mode

Select an observation mode from the Observation mode on the Settings menu.
Figure 4.2.6 Setting an Observation Mode (Standard Mode)
In the observation mode in Figure 4.2.6, Setting an observation mode, the standard mode is
check-marked.
Change to the observation mode well-suited for a given specimen.
1. Standard Mode This mode is well-suited for observing industrial materials, including
metals such as gold, silver, copper, and iron. Among industrial materials, if fabrics,
semiconductors, and polymer materials are to be observed, image shifts can occur as if the
image was moving when there are brightness/contrast changes or the brightness changes
with the passage of time when no operations are performed. In such a case, the use of the
charge-up reduction mode is recommended.
2. Charge-up Reduction Mode When an observation is conducted in standard mode on
water-rich materials, such as organisms and food items, image shifts can occur as if the
image was moving when there are brightness/contrast changes or the brightness changes
with the passage of time when no operations are performed. The charge-up reduction mode
is well-suited for observing these specimens. However, for observing such specimens for a
long time, an observation should be performed by dehydrating the specimens.
NOTE : The charge-up reduction mode can shorten the life of the filament.
