Chapter 5 Maintenance
The rugged and simple design of the Bird 4304A means that it requires minimal
routine maintenance.
Cleaning
It is important to keep the following surfaces clean:
•
Socket bore
•
DC contacts on the element
•
Teflon insulators
If any of the contacts or line connectors are dirty, clean them with a cotton swab
dipped in commercial contact cleaner or isopropyl alcohol.
If the RF line section seems dirty, do not loosen any connections. Clean accessible
components as described above and use dry, clean air to blow out the interior.
The outside of the meter housing can be cleaned with a soft cloth dampened
with a mild detergent solution. Do not wipe the meter glass with a dry cloth, or a
static charge could develop that would cause an erroneous meter indication.
Troubleshooting
The following table contains troubleshooting information for problems that can
occur during normal operation. Find the problem on the table, review possible
causes, and perform the corrective action listed.
WARNING
Never attempt to connect or disconnect RF equipment from the transmission
line while RF power is being applied.
Leaking RF energy is a potential health hazard.
CAUTION
Do not drop. Calibration could be disturbed or the meter could be damaged
as a result.
CAUTION
Do not attempt to remove the RF center conductor.
This will damage the line section.
