This section describes the guidelines and procedures of maintenance, which will ensure fault-free operation of the Analyzer.
The maintenance of the Analyzer consists of cleaning the instrument, factory calibrations, and regular performance tests.
Instrument Cleaning
This section provides the cleaning instructions required for maintaining proper operation of the Analyzer.
To remove contamination from parts other than test ports or any connectors of the Analyzer, wipe them gently with a soft cloth that is dry or wetted with a small amount of water and wrung tightly.
It is essential to always keep the test ports clean, as any dust or stains on them can significantly affect the measurement capabilities of the instrument. To clean the test ports (as well as other connectors of the Analyzer), use the following procedure:
•Using compressed air, remove or loosen the contamination particles.
•Clean the connectors using a lint-free cleaning cloth wetted with a small amount of ethanol and isopropyl alcohol (when cleaning a female connector, avoid snagging the cloth on the center conductor contact fingers by using short strokes).
•Dry the connector with low-pressure compressed air.
Always completely dry a connector before using it.
Never use water or abrasives for cleaning any connectors on the Analyzer. Do not allow alcohol contact on the surface of the connector.
When connecting male-female coaxial connectors, always use a calibrated torque wrench.
WARNING |
Never perform cleaning of the instrument if the power cable is connected to the power outlet. Never clean the internal components of the instrument. |
Factory Calibration
Factory calibration is a regular calibration performed by the manufacturer or an authorized service center. It is recommended to send the analyzer for factory calibration every three years.
Performance Test
The performance test is done to verify that the performance of the Analyzer is up to the published specifications.
A performance test of the Analyzer should be performed in accordance with Performance Test Instructions.
The performance test period is one year.
