Use, Maintenance, and Care of the Devices 3Keysight 11904S User’s and Service Guide 33Gaging ProceduresGaging 2.4 mm and 2.92 mm connectors1 Select the proper gage for your connector. The 2.92 mm connectors are gaged with the samegages and in the same way as the precision 3.5 mm connectors. These are not the same gagesthat are used for the 2.4 mm connectors.2 Inspect and clean the gage, gage master, and device to be gaged. Refer to “Visual Inspection”on page 25 and “Cleaning the Connectors” on page 30 earlier in this chapter.3 Zero the connector gage (refer to Figure 3-3):a While holding the gage by the barrel, and without turning the gage or the device, connectthe gage to the gage master by interconnecting the male and female connectors. Connectthe nut finger-tight. Do not overtighten.b Using an open-end wrench to keep the device body from rotating, use the torque wrench,included in the kit, to tighten the connecting nut to the specified torque. Refer to “Finalconnection using a torque wrench” on page 36 for additional information.c As you watch the gage pointer, gently tap the barrel of the gage to settle the reading.The gage pointer should line up exactly with the zero mark on the gage. If not, adjust thezero set knob until the gage pointer lines up exactly with the zero mark.d Remove the gage master.4 Gage the device connector (refer to Figure 3-3):a While holding the gage by the barrel, and without turning the gage or the device, connectthe gage to the device by interconnecting the male and female connectors. Connect the nutfinger-tight. Do not overtighten.b Using an open-end wrench to keep the device body from rotating, use the torque wrench,included in the kit, to tighten the connecting nut to the specified torque. Refer to “Finalconnection using a torque wrench” on page 36 for additional information.c Gently tap the barrel of the gage with your finger to settle the gage reading.CAUTION Never connect a 2.4 mm gage to a 2.92 mm device. You must use 3.5 mm gages to measure thepin depth of 2.92 mm devices.NOTE Always hold a connector gage by the gage barrel, below the dial indicator. This gives the beststability, and improves measurement accuracy. (Cradling the gage in your hand, or holding it bythe dial applies stress to the gage plunger mechanism through the dial indicator housing.)NOTE Refer to Table 3-1 on page 36 for the connector type and torque setting information.
