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.
