1-10 Preventive Maintenance
Site Master preventive maintenance consists of cleaning the unit 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 and a mild cleaning solution.
Clean the RF connectors and center pins with a cotton swab dampened with denatured
alcohol. Visually inspect the connectors. The fingers of the N(f) connectors and the pins of the
N(m) connectors should be unbroken and uniform in appearance. If you are unsure whether
the connectors are undamaged, gauge the connectors to confirm that the dimensions are
correct.
Visually inspect the test port cable(s). The test port cable should be uniform in appearance,
and not stretched, kinked, dented, or broken.
1-11 Calibration Requirements
Anritsu recommends annual calibration and performance verification by local Anritsu
service centers. The Cable and Antenna Analyzer mode requires calibration standards for
OPEN, SHORT, and LOAD (OSL) or InstaCal module, which are sold separately.
1-12 Annual Verification
Anritsu recommends an annual calibration and performance verification of the Site Master
and the OSL calibration components and InstaCal module by local Anritsu service centers.
The Site Master is self-calibrating and there are no field-adjustable components. The OSL
calibration components are crucial to the integrity of the calibration. As a result, they must be
verified periodically to ensure performance conformity. This is especially important if the
OSL calibration components have been accidentally dropped or over-torqued.

Caution To avoid damaging the display or case, do not use solvents or abrasive cleaners.
Note
Anritsu recommends allowing the instrument to warm up to typical operation
temperature (~15 minutes) before calibrating.
