Test pictures generated by a manually
controllable source
An external picture generator (could be a computer) is
used to provide the test pictures for the ACTAS. The test
picture can not be changed upon request of the ACTAS,
as it is not connected directly to the ACTAS Interface but
indirectly via a projector. However, the output level can
be switched to the low or high light level by means of
manual operations. This should be done in accordance
with the prompt messages displayed on the ACTAS
Control Unit.
When the message 'Set source to 20%' is displayed, the
user has to switch on the low light test picture. When it
is ready, press the <
ENTER
> key, the adjustment will be
carried out automatically in case the adjustment mode is
set to 'Auto' (please refer to Page 2-11).
When the message 'Set source to 60%' is displayed, the
user has to switch on the high light test picture. When it
is ready, press the
<ENTER>
key, the adjustment will be
carried out automatically in case the adjustment mode is
set to "Auto".
When the
<EXIT>
key is pressed, the adjustment pro-
cess will be stopped.
Test pictures generated by a fixed source
A fixed source instead of a manually controllable source
is used to provide the test pictures for the ACTAS. It is
also not connected to the ACTAS Interface through
RS232 communication. The output level of the test
picture can not be changed. The ACTAS imitates the
high and low light level switching by manipulating the
contrast setting.
This method normally lacks precision, and is mainly
reserved for internal evaluation purposes.
