Operating Instructions
Normal
Operation
CAUTION
Do not operate this equipment over the rated 1000
watts continuously. Damage to the resistive element
will result.
The load has no indicators or operating controls, therefore it
requires no special operating procedures or surveillance
when the stated performance limits are not exceeded. Fol-
low the instructions pertaining to the specific transmitting
equipment.
Operation
Under
Abnormal
Conditions
WARNING
Using this load in the upper end of its power
dissipation range will cause the housing to become hot!
Care should be exercised in touching it.
These units will sustain an input moderately greater than
1000 watts for short periods of time. Such loading must be
spaced at reasonable intervals to allow sufficient time for
the load to cool to a safe temperature. The load can, for in-
stance, sustain an input of 1200 watts for a maximum of
five minutes with an interval of at least 30 minutes between
each power application.
Shutdown
These loads, being passive devices, have no way of being
turned off. Their source of RF power must be turned off in-
stead.
