Power
This switch controls the power to the
IR-1000
. The green
light indicates when the power is on.
Test
The
TEST
switch provides a 10-step stair pattern for
rapid calibration or troubleshooting of the attached equipment
such as a monitor or frame grabber. With the
TEST
switch
on, adjust the monitor or frame grabber until the whitest step
is just under the point of saturation and the darkest step is as
dark as possible while visible without clipping.
Gain
The
GAIN
of the
IR-1000
can be either in a manually
adjustable or in an automatic mode. In
AUTO
, the output of
the camera is determined by the internal automatic gain
control (AGC) circuitry, which will adjust the camera gain in
order to keep the output signal at a full level. This is
particularly useful when viewing low contrast highlights and
rotating the Black Level control to stretch the low contrast
highlights into a signal that is easier to examine.
