3. Connect the multimeter test leads

across the center and outer conductor

of the load resistor. Refer to figure 5.

4. Record the value of the resistance be-

fore the load is put into service. Com-

pare the subsequent values with the

latest reading. If the values vary more

than 2 ohms, this could be an indica-

tion of a failing resistive element.

Note: It is recommended that this resistance

check be performed each time the load is to be

used.

RF Connector

Tools Required: Screwdriver

The connector is a “Quick-Change” design which permits

easy interchange with the use of only a screwdriver. For re-

placement, proceed as follows:

1. Remove and retain the four screws

from the corners of the RF connector.

2. Pull the connector straight out of its

socket.

3. Insert the new connector into the mat-

ing connector. Be sure the projecting

center pin on the connector is properly

engaged and seated in the mating

socket, then push it in firmly.
