Safety Precautions
The following are general safety precautions that are not necessarily
related to any specific part or procedure, and do not necessarily appear
elsewhere in this publication. These precautions must be thoroughly
understood and apply to all phases of operation and maintenance.
WARNING
Keep Away From Live Circuits
Operating Personnel must at all times observe general safety
precautions. Do not replace components or make adjustments to the
inside of the test equipment with the high voltage supply turned on.
To avoid casualties, always remove power.
WARNING
Shock Hazard
Do not attempt to remove the RF transmission line while RF power
is present.
WARNING
Do Not Service Or Adjust Alone
Under no circumstances should any person reach into an enclosure
for the purpose of service or adjustment of equipment except in the
presence of someone who is capable of rendering aid.
WARNING
Safety Earth Ground
An uninterruptible earth safety ground must be supplied from the
main power source to test instruments. Grounding one conductor of
a two conductor power cable is not sufficient protection. Serious
injury or death can occur if this grounding is not properly supplied.
WARNING
Resuscitation
Personnel working with or near high voltages should be familiar
with modern methods of resuscitation.
WARNING
Remove Power
Observe general safety precautions. Do not open the instrument
with the power on.

Safety Symbols
Note: Calls attention to supplemental information.
Warning Statements
The following safety warnings appear in the text where there is dan-
ger to operating and maintenance personnel, and are repeated here
for emphasis.
On pages 3and 11.
On page 21.
WARNING
Warning notes call attention to a procedure, which if not correctly
performed, could result in personal injury.
CAUTION
Caution notes call attention to a procedure, which if not correctly
performed, could result in damage to the instrument.
WARNING
Exposure to RF power radiation and the possibility of RF shock or
burns exists with some operating conditions. Always be sure to
turn off the transmitter when connecting or disconnecting a
wattmeter.
Be sure the transmission line is terminated into a load or antenna.
When a Plug-In Element is removed from the RF line socket, the
line section center conductor is exposed. Do not put fingers or other
objects into the Plug-In Element socket while RF power is applied.
WARNING
Always be sure transmitter power is off before disconnecting the
unit from the transmission line.
iii
Caution Statements
The following equipment cautions appear in the text and are repeated
here for emphasis.
On page 3.
On page 4.
On pages 11 and 23.
On page 11.
On page 16.
On page 28.
CAUTION
Do not drop the Thruline Wattmeter or its elements or subject them
to hard blows. The microammeter is shock mounted in the wattmeter
housing, but its delicate mechanism may be damaged by severe impact.
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.
