Specifications
Use of Analytical Module Hardware Test Box, continued
• Gas Pressure Gauge – Shows the internal pressure of the
pneumatic system of the test box.
• Vent Line – This connection is used to release pressure from the
box when the main valve setting is set to vent.
• Valve 1 Switch – This is used to test for leaks on the actuation
lines of the Model 50 as well as manifold ports 1 and 2 on the
module.
• Valve 2 Switch – This is used to test for leaks on the detector
reference path as well as manifold ports 10 and 12 on the
module.
• Valve 3 Switch – This is used to test for leaks on all Model 50
valve ports as well as manifold ports 3, 4, 7, 8, 9, and 11 on the
module.
• Ohm Meter Connection – These jacks are used to connect an
external Ohm meter or multimeter to the device in order to check
the electrical integrity of the TCD beads.
When blank manifold plates are removed in order to install a module,
they should be placed on a clean dry surface such that they will not get
damaged.
Note
• Manifold – The manifold is where the analytical module mounts
for testing. When the Module Tester is shipped it has two blank
plates installed on the manifold. When a single module is tested,
the right manifold is removed. When a double module is tested,
both manifolds are removed. When the device is stored both
blank plates are to be installed on the device in order to protect
the manifold.
The Module Tester manifold is equipped with several o-rings. These
must remain in place for the leak check to work. If an o-ring is damaged
or missing it must be replaced. Refer to spare parts list for appropriate
replacements.
