The following section identifies potential system issues and provides possible resolutions. The waveforms

on the graph of each moisture measurement can indicate whether an issue needs to be addressed. If

you are unable to resolve an issue after following the suggestion shown in this section, contact AMI for

further support.

Graph with No Discernable Peaks or Waveforms

Potential Issue

A graph with no visible waveforms and having no signature H

O and CH

peaks is indicative of either

Laser Failure

Detector Failure

Detector Misalignment

Resolution

Stop using

THE BARRACUDA MODEL 4010LX

for trace moisture measurements and contact AMI for

support.

Waveform with Signature Moisture Peak but No Signature CH

(Methane) Peak

Moisture

Peak

is present

Absorption

Waveform

is normal

Potential Issue

Whenever a waveform appears with the signature moisture peak but is missing the signature CH

peak, it

may indicate an issue with the

Laser Power

or the

Gas Sample

entering the Analyzer.
