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:
z
Socket bore
z
Element body circumference
z
Bottom rim of the socket in the line section
z
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 detergent 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 open-
ing when the element is removed.
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.
