2.4 mm Test Port Connectors

1.Incline the rear of the test set approximately four inches and support it with a stable, solid object (such as a thick book).

2.Using a 9/16-inch open-end wrench, unscrew the test port connector nut.

3.Pull out the center conductor assembly and replace it with a new assembly. Do not touch either end of the new assembly. Part numbers for the test port connector components are located on page 7-16.

4.Replace the test port connector nut and torque it to 562 N-cm (50 in-lb).

5.Measure the pin depth of each port using a 2.4 mm female pin-depth gage. Refer to the connector care information in the calibration kit manual for more information about using the gage.

If the center pin protrudes, or if the depth is less than 0.0001 inch, remove the connector assembly and increase or decrease shims to adjust the pin depth to between 0.0001 and 0.0007 inch. When measuring the pin depth be sure to include the uncertainty calculation of your gage.

6. If you added or removed shims, regage the test port connector assembly.
