Operating Instructions
Controls The only operating control is the range selector switch on
the lower right hand face of the meter unit. No adjust-
ment or control settings are required.
Start-Up Connect the load to the transmitting equipment under
test with 50 ohm coaxial cable (RG-8A/U, RG-9/U,
RG-213/U or equal) equipped with a Male N type plug
(UG-21E/U or equal) which mates with the RF input con-
nector of the load for Models 6732B, 6734B and
6734B-030. For Models 6735-300A, 6736A, 6736-030A,
6737A and 6737-030A use a cable equipped with a Male
LC type plug. After the transmitter has been connected to
the load, proceed according to the transmitter manufac-
turer’s instructions. When reconnecting the antenna, it
may be necessary to slightly adjust the transmitter due
to possible differences in VSWR between the load and the
antenna system.
Normal
Operation
Each Termaline Wattmeter will continuously measure
and safely dissipate RF power up to its maximum rating.
To operate, set the range selector switch to the desired
power range and turn on the RF power source. The RF
power absorbed by the load portion will be displayed on
the meter. Read the power level from the scale that
matches the range set by the range selector switch. For
Models 6737A and 6737-030A set the water rate to at
least ½ gallon/minute (2 liter/minute).
WARNING
When the unit is used in the upper range of its power
capacity, the radiator will become hot - care should be
used in touching the equipment.
WARNING
Do not attempt to operate the Termaline Wattmeter for
prolonged periods at higher than rated load levels.
Damage to the equipment and injury to operator may
result.
