Preventive Maintenance
Preventive maintenance consists of checking the front panel connectors. This should
be done at least every six months — more often if the test set is used daily on a
production line or in a harsh environment.
Visually inspect the front panel connectors. The most important connectors are
those to which the DUT is connected. All connectors should be clean and the center
pins centered. The fingers of female connectors should be unbroken and uniform in
appearance. If you are unsure whether the connectors are good, gauge the
connectors to confirm that their dimensions are correct.
CAUTION Never connect 50 ohm cables to the front panel 75 ohm connectors of the analyzer
or test set. Otherwise, irreparable connector damage will occur.
Cleaning the Test Set
Use a dry cloth or one slightly dampened with water to clean the external case parts.
Do not attempt to clean internally.
WARNING To prevent electrical shock, disconnect the test set from power mains before
cleaning.
