1-3 Instrument Care and 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 with a cotton swab dampened with denatured
alcohol. Visually inspect the connectors. If you are unsure whether the
connectors are undamaged, 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 the test port
cable remain in good condition.
ESD Caution
The Site Master, like other high performance instruments, is
susceptible to electrostatic discharge (ESD) damage. Coaxial cables and
antennas may build up a significant static charge, which may damage
the Site Master. To prevent ESD damage, users are advised to connect a
short to either end of the cable before connecting the cable to the Site
Master. If no short is available then a termination (load) may be used.
Site Master operators must always be aware of the potential for ESD
damage and take all necessary precautions. Operators should exercise
practices outlined within industry standards such as JEDEC-625
(EIA-625), MIL-HDBK-263, and MIL-STD-1686; which pertain to ESD
and ESDS devices, equipment, and practices. It is important to
remember that the operator may also carry a static charge that can
cause damage. Following the practices outlined in the above standards
will ensure a safe environment for both personnel and equipment.
Caution
To avoid damaging the display or case, do not use solvents or
abrasive cleaners.
