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 D-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.
