1-6 Preventive Maintenance
Site Master preventive maintenance consists of cleaning the instrument and
inspecting and cleaning the RF connectors on the instrument and all
accessories. Clean the Site Master with a soft, lint-free cloth dampened with
water or water plus a mild cleaning solution.
Clean the RF connectors with a cotton swab dampened with denatured
alcohol. Visually inspect the connectors. If you are unsure whether the
connectors are undamaged, then gauge the connectors to confirm that the
dimensions are correct.
Carefully inspect the test port cable. The cable should be uniform in
appearance, and not stretched, kinked, dented, or broken. A defective test
port cable is the most common cause of unreliable or erratic measurements.
Extra care should be exercised to ensure that the test port cable remains in
good condition.
1-7 Annual Verification
Anritsu recommends an annual calibration and performance verification of
the Site Master by local Anritsu service centers.
The Site Master is self-calibrating and there are no field-adjustable
components. The external calibration components are crucial to the integrity
of the user calibration. As a result, they must be verified periodically to
ensure performance conformity. This is especially important if the calibration
components have been accidentally dropped or over-torqued.
