Maintenance
Maintenance
Only qualified persons familiar with the hazards involved with high-voltage test equipment should perform
maintenance. Read and understand Sections 1, 2, 3, 4, and 5 before performing any service.
The TTRU1 requires only periodic inspection. Inspect all hardware items to ensure all are in good condition.
The TTRU1 may be cleaned periodically. In so doing, do not allow water to penetrate panel holes. An all-purpose,
household spray cleaner can be used to clean the panel. Polish with a soft, dry cloth. Clean the cables and mating
panel receptacles with isopropyl or denatured alcohol applied with a clean cloth.
Calibration
A complete performance and calibration check should be made at least once every year. This will ensure that the
TTRU1 is functioning properly over the entire measurement range. The TTRU1 calibration is performed on each new
or repaired unit before sending it to a customer.
