Chapter 5 Maintenance
Cleaning
If any of the contacts or line connectors become dirty, they should be cleaned
with a good contact cleaner or dry cleaning solvent on a cotton swab stick.
It is important to keep the following surfaces clean:
•
Socket bore
•
Element body circumference
•
Bottom rim of the socket in the line section
•
DC contacts on the element
Take care not to disturb the spring finger of the DC contact when cleaning the
socket bore. The spring finger can be manually adjusted. The button must be
pushed out far enough to make good contact with the element body but it must
not restrict the entry of the element.
Clean the meter and meter housing using a cloth moistened with a mild deter-
gent solution. Do this only when necessary and take care not to allow water to
enter any of its circuitry as damage may result.
Preventative Maintenance
Care and maintenance required for the 4314B Thruline Wattmeter is primarily
limited to cleaning. Keeping the Plug-In Element in the socket of the line section
as much as possible serves as an effective seal against the entry of dust and dirt
and to prevent damage to the meter. An aluminum dust plug may be used to
cover the socket opening when the element is removed.
Line Section Care
The RF connectors on the line section should also be protected against the entry
of dust and dirt by keeping them covered when the wattmeter is disconnected
from the RF line.
CAUTION
Use reasonable care in handling. Do not drop or subject the wattmeter or
elements to hard blows as accuracy may be impaired or other damage could
result.
