The slide is not completely symmetrical. When properly installed, the front edge of the slide
is even with the edge of the slide holder when the slide is fully closed. When the slide is fully
opened, the back of the slide sticks out past the back of the holder.
Adjust the slide release mechanism so that a slight movement of the release button will free
the slide. The adjustment is made by moving the two stop nuts (which press against the
spring) up or down on the long screw which presses against the slide.
To install a meter, slip it over the studs in the cover, put on the flat washers and the lock
washers, and tighten the nuts
lightly to prevent fracturing the meter plastic. Place the meter
retainer over the studs at the front of the meter and, while pressing the retainer back against
the meter, tighten the hex spacers on the studs.
When reassembling the cover and main board together, guide the three Light Switch pins into
the mating connector. When installing the knob on the Function Switch, make sure it is
oriented properly.
The following steps may be used as a guide to resassembling the chamber :
1. Screw in the guarded feedthrough from the top of the chamber assembly.
2. Press the three nylon shoulder washers into the holes in the chamber plate. The widest
washer diameter must be on the chamber side.
3. Insert the three screws from inside the chamber up through the nylon washers. Hold
them in place.
4. Place the insulating disk over the three screws.
5. Place the metal cup over the three screws. Make sure the opening matches the opening
in the chamber.
6. Install lock washers and nuts on the screws. Tighten firmly.
7. With an ohm meter, check that a complete open circuit exists between the metal cup
and the body of the chamber.
8. Screw the center electrode disk onto the center pin of the guarded feedthrough. The
small diameter hub goes toward the electronic section. Hold the center pin with a pair
of pliers and tighten the disk.
9. Install the chamber circuit board and fasten it with lock washers and nuts. Solder in
the connections to the guarded feedthrough.
10. Gently plug the cable onto the battery/connector board and fasten the board to the
chamber with the screws and lock washers.
11. Use one-mil (0.001 inch, 25 micron) aluminized Mylar for the chamber face. If only
one side has aluminum on it, make sure that side is toward the inside of the chamber.
Lay the Mylar on the chamber and slip the clamp ring over it, making as smooth a face
as possible.
