Maintenance and Troubleshooting Information
Troubleshooting the Instrument
The advanced design of the RMLD-IS makes it one of the most reliable leak survey
instruments available. However, should you experience problems with the instrument or
suspect that the instrument is not operating properly, do not use the instrument for leak
survey work until the problem is resolved.
Only a qualified RMLD-IS repair technician should attempt to repair or adjust the
instrument. There are no user serviceable components in the RMLD-IS that can be
repaired or replaced.
Most often, a problem has a simple cause. The following table provides a list of common
problems, cause and solution. Should you have a problem not listed or the solution
doesn’t work, please contact HEATH for further assistance.

and will not pass the Self-
Test
 Laser calibration has
drifted
• Run Self-Test and use
the override function
Have to use Self-Test
override each time the
Self-Test is performed
 Laser calibration has
