(5-3) Level setting
The level setting is mostly divided into the
following two groups:
●
Gain setting
This is to set the gain (amplification ratio)
of the preamplifier between the CCD
imaging device inside the camera to A/D
converter.
●
Offset setting
This is to set the offset of the preamplifier
between the CCD imaging device inside the
camera to A/D converter.

Refer to the next section (Section 6) for
the specific setting method.
(Note) As for the offset setting, it is
recommended to use the factory
default setting except for a special
case.
(5-4) Program page setting
The FC series cameras incorporate nonvolatile memories
and various operation mode settings and level settings can
be stored in them.
The setting items are stored in the virtual pages (hereinafter
referred to as “program pages”) inside the camera.
This camera has 6 program pages of “A”, “B”, “C”, “D”, “E”
and “F” (right figure).
The camera starts operating according to the various
settings stored in the relevant page when the mode switch is
at any one of the positions from “A” to “F” at the time of
power-on.
The camera starts operating according to the settings stored
in the page “A” when the mode switch is at any position other
than those from “A” to “F” at the time of power-on.
