2. Turn off the sample valve at the tap in accordance with site lock-out,
tag-out rules.
3. Disconnect the gas sampling line from the supply port of the
analyzer.
4. Wash the sampling line with alcohol or acetone and blow dry with
mild pressure from a dry air or nitrogen source.
5. Once the sampling line is completely free of solvent, reconnect the
gas sampling line to the supply port of the analyzer.
6. Check all connections for gas leaks. Using a liquid leak detector is
recommended.
Excessive Sampling Gas Temperatures and
Pressures
The embedded software is designed to produce accurate measurements only
within the allowable cell operating range (see Appendix A). Pressures and
temperatures outside these ranges will trigger a P/T Fail Error fault.
Electrical Noise
High levels of electrical noise can interfere with laser operation and cause it to
become unstable. Always connect the analyzer to a properly grounded power
source.
Cleaning the Mirrors
If contamination makes its way into the cell and accumulates on the internal
optics, a Power Fail Error will result. If mirror contamination is suspected,
refer to “Service” on page B - 17 before attempting to clean the mirrors. If
advised to do so, use the following procedure.
If the pressure, temperature, or any other readings on the LCD
appear suspect, they should be checked against the specifications
(see Appendix A).
Do not attempt to clean the cell mirror until you have consulted
with
“Service”
on page B - 17 and have been advised to do so.
The sample cell assembly contains a low-power, 10 mW MAX, CW
Class 3b invisible laser with a wavelength between 700 to
3000 nm. Never open the sample cell flanges or the optical
assembly unless the power is turned off.
