Using the connector gage
Measuring connectors
Measuring the recession of the center conductor behind the outer conductor
mating plane in a connector is done in exactly the same way as zeroing the gage,
except of course that the graduated dial is not re-set when the measurement is
made.
If the connector has a retractable sleeve or sliding connector nut — precision
7 mm connectors, for example — extend the sleeve or nut fully. This makes it
easier to keep the gage centered in the connector.
Hold the gage by the plunger barrel and slip the gage into the connector so that
the gage plunger rests against the center conductor. Carefully bring the gage into
firm contact with the outer conductor mating plane.
NOTE
Gages should be checked often, to make sure that the zero setting has not
changed. Generally, when the gage pointer on a gage that has been zeroed
recently does not line up exactly with the zero mark, the gage or calibration
block needs cleaning. Clean carefully and check the zero setting again.
