AQUATRAN Model 3/40 Operator's Manual
The Advanced Test Method allows the user to specify all of the parameters and conditions used to
perform a permeation test. An Advanced Test Method allows the most flexibility in determining how
a permeation test will be executed. The Advanced Test method also allows Test Sequencing.
Saved Test Methods
Saved Test Methods are Advanced Test Methods that have been saved and can be recalled for later
use. Saved test methods are accessed using the "Methods" control displayed at the bottom of any
Advanced Test Method screen.
Using Test Sequencing
The Sequential Testing function allows a series of tests to be performed on the same samples at different
test conditions (Temperature and RH). Once started a sequential test series will execute all of the tests in
the Sequential Test Parameters table without requiring user intervention.
The series of tests to be executed is defined by enabling the Sequential Test function in an Advanced Test
method and defining the individual test conditions using the Sequential Test Parameters Table. For more
information see "How Sequential Testing Works" in Appendix D.
Humidified Environment Testing
The AQUATRAN Model 3/40 has the capability of generating a controlled RH for the Test Gas. For the
minimum RH that can be generated refer to the section on "Sample Conditioning Capabilities" in Chapter
10.
Humidified Test Gas is created using a steam generator to add water vapor to dry compressed air.
Before starting a test using Generated RH the water levels in the reservoirs should be checked and filled if
necessary.
With Reclaiming Water, the water consumption for Test Gas RH generation is approximately 7.0 L/month at
37.8 °C and 90% RH. The reservoir capacity is approximately 5 Gallons (19 Liters). For Test Gas RH
generation standard distilled water can be used.
Filling the Test Gas Water Reservoir
The Test Gas Water Reservoir should be checked periodically and filled if necessary. Follow these steps to
fill the Test Gas Water Reservoir:
Note: The Test Gas Water Reservoir is a plastic container located outside of the instrument.
1.
Check the water level in the Test Gas Reservoir to determine if it is sufficient to perform the
test.
2.
Remove the cover from the reservoir. The filter may be removed to make adding the water
more convenient if desired.
3.
Add water as necessary to fill the reservoir.
4.
Place the filter inside the reservoir and securely tighten the cover.
