Troubleshooting
With its advanced design, the Gas Laser is one of the most reliable meth-
ane detection instruments available. Should you experience problems, there
is most likely a simple cause. The following table provides a list of common
problems, cause and solution.
Should you have a problem not listed, or the recommended solution doesn’t
work, please contact Teledyne GMI Customer Service for further assistance.
Do not use the instrument for scan work until the problem is resolved.
Symptom Probable Cause(s) Solution
Higher than normal short range, and
lower than normal long range readings
Laser calibration has drifted Run Self Test
Concentration reading is low
and will not pass the Self Test
Laser calibration has drifted Run Self Test up to three (3) times and then
contact Teledyne GMI Customer Service
Unit will not turn on Low battery Replace or recharge battery pack
Continual warning sound or screen
notification when scanning
Scanning at distance beyond Gas Laser range Move closer to the target
Background surface is absorbing or reflecting the
IR light level
Change angle to target to get a better reflecting
background
Low battery Check battery level and recharge if necessary
Excessive false detection while
scanning at longer distances
Scanning too fast - Slow down the scanning rate
- Pause at the long range and sweep towards you
Alarm detection threshold set too low Increase the Alarm detection threshold
Scanning at the instrument’s range limit Move in closer
Excessive false detection while
scanning at closer distances
Scanning too fast Avoid making abrupt motions while scanning
Alarm detection threshold set too low Increase the Alarm Detection Threshold
Excessive false detection or
loss of sensitivity
Laser output not optimized Perform Self Test procedure
Alarm Detection Threshold is too high or low for
conditions
Check the Alarm Detection Threshold
Error message or Warning icon
on continuously
Low battery Check battery level and recharge if necessary
Moisture condensation on mirror due to rapid
change in temperature
Allow for the instrument temperature to stabilize
Internal component failure Note error message and contact Teledyne GMI
Reduced run time
Battery not fully charged Charge battery pack until solid green light on
charger is on
Diminished battery capacity Replace battery pack, and properly dispose of
exhausted battery pack
Low Signal or Low Light
Background surface is absorbing or reflecting the
IR light level
Change angle to the target for a better background
Scanning at the range limit of the instrument Move in closer
Saturated Background surface is reflecting the IR light level Change angle to the target for a better background
