Using Connector Gages
Using Connector Gages
Before a connector gage is used, it must be inspected, cleaned, and
zeroed.
Inspecting and Cleaning the Gage
Inspect the connector gage and the gage calibration block carefully,
exactly as you have inspected the connector itself. Clean or replace the
gage or the block if necessary (dirt on the gage or block will make the
gage measurements of the connectors inaccurate and can transfer dirt to
the connectors themselves, damaging them during gaging or when the
connection is made).
Zeroing the Gage
Zero the gage by following the steps described below. Be sure that you
are using the correct connector gage and correct end of the gage
calibration block for the connector being measured.
• Hold the gage by the plunger barrel (not the dial housing or cap) and,
for male connectors, slip the protruding end of the calibration block
into the circular bushing on the connector gage. For precision 7mm,
female precision 3.5mm use the flat end of the gage calibration block.
For female Type-N connectors, use the recessed end of calibration
block.
• Hold the gage by the plunger barrel only (Figure E-6). Doing so will
prevent errors in gage readings due to the application of stresses to
the gage plunger mechanism through the dial indicator housing.
• Carefully bring the gage and gage block together, applying only
enough pressure to the gage and gage block to result in the dial
indicator pointer settling at a reading.
