3-10 85054BUse, Maintenance, and Care of the DevicesGaging ConnectorsGaging Female Type-N ConnectorsNOTE Always hold a connector gage by the gage barrel, below the dial indicator. Thisgives the best stability, and improves measurement accuracy.1. Select the proper gage for your connector. (Refer to Table 6-2 for the gage set part number).2. Inspect and clean the gage, gage master, and device to be gaged. Refer to “VisualInspection” and “Cleaning Connectors” earlier in this chapter.3. Zero the connector gage (refer to Figure 3-4):a. While holding the gage by the barrel, and without turning the gage or the gage master,screw the gage connecting nut onto the female gage master, just until you meetresistance. Connect the nut finger-tight. Do not overtighten.b. Use the torque wrench recommended for use with this kit to tighten the connecting nut to135 N-cm (12 in-lb). Refer to “Connections” on page 3-16 for more information.c. Loosen the dial lock screw on the gage and rotate the gage dial so that the pointercorresponds to the correction value noted on the gage master. Do not adjust the gagedial to zero, unless the correction value on the gage master is zero.d. Tighten the dial lock screw and remove the gage master.e. Attach and torque the gage master to the gage once again to verify that the setting isrepeatable. Remove the gage master.4. Gage the device connector (refer to Figure 3-3 on page 3-9):a. While holding the gage by the barrel, and without turning the gage or the device, screwthe gage connecting nut onto the device being measured, just until you meet resistance.Connect the nut finger-tight. Do not overtighten.b. Use the torque wrench recommended for use with this kit to tighten the connecting nut to135 N-cm (12 in-lb). Refer to “Connections” on page 3-16 for more information.c. Gently tap the barrel of the gage with your finger to settle the gage reading.d. Read the gage indicator dial. If the needle has moved clockwise, the center conductor isprotruding by an amount indicated by the blacknumbers. If the needle has movedcounterclockwise, the center conductor is recessed by an amount indicated by the rednumbers.For maximum accuracy, measure the connector a minimum of three times and take anaverage of the readings. After each measurement, rotate the gage a quarter-turn toreduce measurement variations that result from the gage or the connector face not beingexactly perpendicular to the center axis.e. Compare the average reading with the observed pin depth limits in Table 2-2 on page2-4.
