Troubleshooting Procedure
When troubleshooting the QML logger, write a failure notice consisting
of the following issues:
- What failed (what worked/did not work)?
- Where did it fail (location and environment)?
- When did it fail (date, immediately/after a while/periodically/
randomly)?
- How many failed (only one defect/other same or similar defects/
several failures in one unit)?
- What was connected to the product and to which connectors?
- Input power source type, voltage and list of other items (lighting,
heaters, motors, et cetera) that were connected to the same power
output.
- What was done when the failure was noticed?
