services.
Environmental
Requirements
The loads should be operated in as clean and vibration free
an environment as possible. The ambient temperature
range should remain within -40°C to +45°C (-40°F to
+113°F) for proper operation.

The models are a self-contained unit, there are no addi-
tional parts other than this instruction book supplied. The

other type of standard connector, then the load should be or-
dered with the appropriate type of mating connector.

Equipment
Only a screwdriver is needed for disassembling for service.
An ohmmeter or resistance bridge with an accuracy of one
percent or better at 50 ohms, is useful for checking resistor
condition.
