Gaging Procedures
Gaging Male Type-N Connectors
NOTE Always hold a connector gage by the gage ba rrel, b elow the dial indica tor.
This gives the b est stability, and improves measurement accuracy.
1. Select the proper gage for your c onnector. (Refer to Table 6-2 for gage part nu mbers).
2. Inspect a nd clean the gage, gage master, and d evice to be gaged. Refer to “Visual
Inspection” and “Cleaning Connectors” earlier in this chapter.
3. Zero the connector gage (refer to Fig u re 3- 3):
a. W hile hold ing the gage by the barrel, and without turning the gage or the gage
master, screw the gage master connecting nut onto the male gage, just until you
meet resistance. Connect the nut finger tight. Do not overtighten.
b. Use the torque wrench recom m ended for use with this kit to tighten the connecting
nut to 135 N-cm (1 2 in-lb). Refer to “Co nnections” on page 3-16 for more informati on.
c. Loosen the dial lock screw on the ga ge and rotate the gage dial so that the pointer
corresp onds to the corr ec tion value noted on the ga ge master. Do not adjust the gage
dial 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 tor que the gage master to the gage once again to verify that the set ting is
repeat able . Remov e the gage master.
4. Gage the device connector (refer to Figur e 3 -3):
a. W hile hold ing the gage by the barrel, and without turning the gage or the device,
screw the connecting nut of the device being measured onto the gage, just until you
meet resistance. Connect the nut finger-tight. Do not overtighten.
b. Use the torque wrench recom m ended for use with this kit to tighten the connecting
nut to 135 N-cm (1 2 in-lb). Refer to “Co nnections” on page 3-16 for more informati on.
c. Gently tap the barrel of the gage with your finger to settle the gage reading.
d. Read the gage indicator dial. If the ne edl e has moved clockw ise, the cent er conductor
is protruding by an amount indicated by the black numbers. If the needle has moved
counterc lockwise, the center c onduct or is recessed by an amount i ndic at ed by the red
numbers.
For maximum accuracy, measure the connector a minim um of three times and ta ke
an average of the readings. After each measur ement, rotate the gage a quarter-turn
to reduc e measurement variati ons that resul t from the gage or t he connector fa ce not
being exactly perpend icular to the center axis.
e. Compare the averag e reading wit h the obser ved pin dept h limits i n T abl e 2-2 on page
2-4.
