Troubleshooting the Instrument
The advanced design of the RMLD 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 repair technician should attempt to repair or adjust
the
instrument.
There are no user serviceable components in the RMLD that can be repaired
or replaced.

problems, cause and solution. Should you have a problem not listed or the
