5. Wash the sampling line with isopropyl alcohol or acetone and blow
dry with mild pressure from a dry air or nitrogen source.
6. Once the sampling line is completely free of solvent, reconnect the
gas sampling line to the sample supply port of the analyzer.
7. Check all connections for gas leaks. SpectraSensors recommends
using a liquid leak detector.
Excessive Sampling Gas Temperatures and
Pressures
The embedded software is designed to produce accurate measurements only
within the allowable cell operating range (refer to the Calibration Certificate).
Pressures and temperatures outside this range will trigger a Pressure Low
Alarm , Pressure High Alarm , Temp Low Alarm , or Temp High Alarm
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 Laser Power Low Alrm fault will result. If mirror contamination is
suspected, please contact Technical Service before attempting to clean the
mirrors. If advised to do so, use the following procedure.
The cell temperature operating range for analyzers that are equipped
with heated enclosures is equal to the enclosure temperature setpoint
±5° C.
If the pressure, temperature, or any other readings on the LCD appear
suspect, they should be checked against the specifications (Refer to the
Calibration Certificate).
This procedure should be used ONLY when necessary and is not
part of routine maintenance. To avoid compromising the system
warranty, refer to “Service Contact” on page B-11 before
cleaning mirrors.
