Description
This module tests the ability of laser power meter (internal
radiometer) 2A1A7 to detect light energy from the flash lamp.
The flash lamp is programmed off, and the output of the internal
radiometer digitized and recorded. The flash lamp is then pro-
grammed on, and the internal radiometer output digitized and
compared with the recorded lamp off output.
If the off output is not +0.0125 to +0.080 vdc higher than the
on output, a prompt is displayed at the completion of the test.
The lamp is then programmed off, and the internal radiometer
output digitized and compared to the previously recorded off
output l
A prompt is displayed if the difference is greater than
+0.002 vdc.
This module checks laser cover assembly 2A1A2A19 and laser power
supply assembly 2A1A6.
An error detected during any of the following checks will dis-
play a prompt at the completion of the test.
The operator opens the laser enclosure, and turns the laser off
switch to OFF.
The laser shield interlock, laser cover assembly
switches, and laser fire switch are checked.
The operator then
closes and locks the laser enclosure, and the above checks are
repeated.
The program then applies logic signals and voltages
(115 vat, -15 vdc and +28 vdc) to check relays and interlocks.
The operator checks for both LASER ARMED lights on. The pro-
grammable pulse generator is programmed for sync signals. The
operator holds the laser fire switch in the on position and the
interlocks and high voltage sample are checked. The operator
then releases the laser fire switch.
Effectivity:
Used with E/O bench equipped with optical signal
analyzer only.
This module tests the ability of bracket assembly 2A1A1A4 to
respond to focus commands.
The focus mechanism is programmed to
the home position and motor status checked.
If motor status is in error, a prompt is displayed at the com-
pletion of the test.
