Use of Analytical Module Hardware Test Box, continued
The following procedure should be used to set up the device for use.
Refer back to figure 4-12.
Setup of Hardware
Tester
Step Procedure
1. Place the test box in a clean dry area that is well ventilated.
2. Set the switches labeled VALVE 1, VALVE 2, and VALVE 3
to OFF. Set switch labeled MAIN VALVE to VENT.
3. For leak checking, connect 1/8” gas supply line to the port
labeled GAS SUPPLY. Turn on gas at supply end.
4. If using a test instrument to detect for leaks, such as a
GOW-MAC, then the vent line on the Module Tester must
be extended away from the box to avoid contamination of
the area being leak checked. The vent line is connected to a
Teflon®) tube that can extend approximately 2 feet away
from the box.
5. If testing TCD beads, connect a test meter (ohm meter or
multimeter set to check resistance) to the jacks labeled
OHM METER.
6. If testing a “single” analytical module (smaller module
configured with one post), then remove the right side blank
plate from the device by removing the M10 x 25 mm bolt.
If testing a “double” analytical module (larger module
configured with two posts), then remove both blank plates.
Notes: To prevent manifold leaks when attaching the Analytical
Module in the following step, ensure that all o-rings are in
place before attaching the module. In addition, torque the
module bolts to between 7.8 and 11.0 ft-lbs.
7. Attach the Analytical Module to the test box using the M10 x
120 mm bolts supplied with the module.
If testing a single module, verify that the blank manifold
plate is properly secured and with proper torque to prevent
leaks.
8. The device is now prepared for testing.
