Teledyne 100AH 9.8 Light Leak Check Procedure

Teledyne API Model 100AH SO2 Analyzer Instruction Manual, 02417, Rev. D

Pressure method:

1. Connect a Leak Checker to the exhaust port of the analyzer. (Refer to Figure 9-3 for

pneumatic diagram.)

2. Pressurize the system and adjust the needle valve such that the gauge pressure does not

exceed 15 PSIG.

3. Apply bubble solution to all the seals, interfaces and fittings to locate the leak.

4. Tighten the seal or fitting until the leak stops.

5. Lastly, drop off any accumulated bubble solution from the sensor assembly.

6. Verify leak by pressurizing the pneumatic system and close the shut-off valve. Turn off the

pump power. If the gauge pressure drops more than 1 in-Hg within 5 minutes, then repeat

steps 2 through 5 until the leak stops.

9.8 Light Leak Check Procedure

1. Scroll the TEST functions to PMT.

2. Input zero gas.

3. Shine a powerful flashlight or portable incandescent light at the inlet and outlet fitting, and at

all the joints of the reaction cell. The PMT value should not respond to the light.

If there is a response, tighten the joints or replace the tubing with new black PTFE tubing.
