Self-help and Diagnostics
Problems in testing may sometimes crop up. If you experience a problem and the problem might
be with the DX, please take the following steps before calling or returning the unit.
By performing these procedures and having the requested information available will help Megger
Service or Applications departments analyze the situation to provide you with an appropriate
response.
You can reach either department at (970) 282-1200 or toll-free at 1 (800) 752-8272 for
assistance.
Step 1: Basic information
Write down all basic instrument information including the following:
Product
Model number
Serial number
NOTE: This information is located on the rear panel label. If the tester has special options installed, please
note the options used. Any information concerning the instrument is helpful. A great tool would be a print
or sketch of the waveforms displayed on the tester.
Step 2: Applications or service problem?
Generally, if you note a problem only when testing a specific motor/generator or other coil type,
then Applications would be involved (refer to the “Applications: What to do first” section).
If you cannot determine that the problem is associated with any one type of motor/generator or
other coil type, then Service would be involved (refer to the “Service: What to do first” section).
