Completed

**Note(s):**

**Never at any point during the test should the technician walk away.
The**

**Technician must pay close attention when the test is being
preformed.**

**Every time this test is performed it should be performed at the same
barometric pressure.**

10.1 Set the Main Valve and Microcalibrator Valve to the closed/off
position. 

10.2 Turn on both the Microcalibrator Power Switch (Panel Front) and the
Sen-I-Tran Power 

Switch (Back Panel).

10.3 Set the bottle pressure gauge regulator to 15psi. 

10.4 Connect a clean dry Argon supply to gas input on the back panel of
the Leak 

Measurement Device. Tighten the connections 1/8 turn past finger tight.

10.5 Open Argon bottle valve. 

**Note(s):**

**Ensure pressure gauge on Argon bottle reads 15psi.**

10.6 Verify the System Pressure Gauge on the back panel reads 12 inches
Water Column. 

10.7 Turn the Main Valve to ON. Turn the Microcalibrator Valve to OPEN.
Flow of gas 

through the Leak Measurement Device shall now occur.

10.8 Open the Flow Adjustment Valve (counter-clockwise) to allow the
mechanical flowmeter 

to reach full scale (130 ccm). The Microcalibrator will give an error
reading at this point

since the actual flow exceeds its working range.

10.9 Turn down the flow rate to the point where the Microcalibrator is
reading 10ccm. This 

procedure verifies that the delivery system is properly working and
allows for purging

of the Leak Measurement Device.

10.10 Turn the Main Valve to OFF.

tube is connected

to which port)

10.13 Verify the Sen-I-Tran (Chamber Pressure) Gauge still reads between
--0.015 and +0.015 inches 

of water.

10.14 Turn the Main Valve to begin the flow. The Microcalibrator should
read 10ccm. To 

pressurize the chamber, increase the gas flow by turning the Flow
Adjustment Valve

until the mechanical flowmeter reads its full value of 130 ccm. The
chamber pressure

should immediately begin increasing. Within a 10-15 minutes the pressure
should read 2.9

inches. When it does, reduce the flow rate gradually so that the target
pressure of 3.00 inches

is gradually approached

10.15 Close the bottle, pressure regulator valve, and microcalibrator
valve. 

10.16 Turn the main valve to gas flashing position to drop the pressure
