CAUTION
Severe damage to the Plug-In Element or wattmeter can result from exposure
to excessive RF power. Make sure the Plug-In Element installed in the
wattmeter has a sufficiently high wattage rating to handle the line load when it
is first applied to 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 may
result.
CAUTION
Do not apply RF power to the wattmeter in excess of the full scale range of the
element.
CAUTION
When making low reflection readings using a more sensitive element, take care
to insert the element so that it senses reflected power only. Do not rotate the
element in the socket so that it is subjected to forward power. This can result in
damage to the Plug-In Element, the microammeter, or both.
CAUTION
If other than Female N type connectors are used, limit power and frequency to
the capabilities of the RF coaxial cable or connectors used. Damage to
connectors or errors in reading could result.
