Operation

Under

Emergency,

Adverse, or

Abnormal

Conditions

The loads of the Series 6700A/B Termaline Wattmeters

will withstand a temporary overload of up to 20 percent

above their nominal maximum rating. The overload

should be applied for no more than five to ten minutes.

Allow at least a half-hour of cooling thereafter before sub

jecting the unit to another overload. For Models 6737A

and 6737-030A, increase the water flow rate for extra

protection. Do not allow the water to reach the boiling

point. If it does, the RF power must be immediately de

creased and/or the water flow rate increased.

It should be understood that although the load portion

can accept a limited overload, the meter is restricted to

the amount of overranging acceptable. Disconnect the me

ter lead from the voltmeter to avoid damage.

Shutdown It is not possible to cut off the flow of RF power into the

load except by turning off the transmitter or RF source.

Turning the range selector switch to OFF merely deacti-

vates the meter without affecting the load.

WARNING

Never attempt to disconnect any RF equipment from

the transmission line while RF power is being applied.

Leaking RF energy is a potential health hazard.

Emergency

Shutdown

Turn off the source of RF power.
