Gaging Procedures
Zeroing Connector Gages
For Type-N gages, the paired gage master is labeled with an offset value to
compensate for its inaccuracy with its gage. This label appears on the bottom
of all Type-N gage masters that have been paired with gages. When setting a
Type-N gage with its master, always set the gage to the master offset value
shown on the label, not to the zero, unless that is the offset value indicated.
The design of the gages used to measure 3.5 mm, 2.92 mm, 2.4 mm, and
1.85 mm connectors are different than the Type-N gage design. The primary
difference is that the Type-N gages require an offset to compensate for
inaccuracies in the gage masters.
1.
Select the proper gage for your connector. Always use gages that are
intended for pin depth measurements. Refer to
for gage model numbers listed with the associated connector
types.
2.
Inspect and clean the gage, gage master, and device to be gaged. Refer to
“Visual Inspection” on page 4-3
“Cleaning Connectors” on page 4-6
3.
While holding the gage by the barrel, attach the gage to the gage master.
Connect the gage master finger tight. Do not overtighten.
4.
Use the torque wrench recommended for use with your connector type to
tighten the connecting nut to the gage master. Refer to
.
5.
Type-N: Loosen the dial lock screw on the gage and rotate the gage dial
so that the pointer corresponds to the correction value noted on the gage
master. Do not adjust the gage dial to zero unless the correction value on
the gage master is zero.
1.85/2.4/2.92/3.5/7 mm: The gage pointer should line up exactly with the
zero mark on the gage. If not, adjust the zero set knob or rotate the gage
dial until the gage pointer lines up exactly with zero.
6.
Tighten the dial lock screw and remove the gage master.
7.
Attach and torque the gage master once again to verify that the setting is
repeatable. Remove the gage master.
For 7 mm connectors, you must remove the collet with the collet extractor
tool prior to performing pin depth measurements.
Before continuing, make sure you are familiar with the proper connection
and torque techniques for your connector type. Refer to
