OPM 3000
Installation
5-2
The zero jig (Figure 5-1) on-line test reflector is inserted over the transceiver
lens. The filters provided are marked in single-pass opacity; this is the same
as double-pass with a correlation factor (OPLR) of 0.50.
1. Hold the zero jig in a position to see the reflector. Turn the fine
adjustment (large knob) so the iris begins to open, exposing more of the
reflector. This direction will cause the monitor to lower opacity. To raise
opacity, turn in the opposite direction so the iris begins to close.
2. Loosen clamps on the transceiver and swing it open.
3. Clean the lens using alcohol and a clean lint free paper that will leave no
film on the lens.
4. Place the zero jig on the two alignment pins (Figure 5-2) with the
reflector facing toward the transceiver (away from the stack).
5. Secure the device to the transceiver by tightening the mounting screw.
6. Using the fine adjustment (large knob) start by raising the opacity level
above zero then slowly turn the knob in the opposite direction to just
reach zero. If you cannot reach zero, or you cannot come above zero,
see "Coarse Adjustments".
7. Place the neutral density slides in the slot provided on the top of the
device just behind the mounting screw. The system should read the
same value written on the label within ±2%.
