Measurement Errors
The gage measures the pin depth (recession) of the
connectors. If the pin depth to too far negative, errors will
result from excessive air gap in the connection.
Connector Damage
If the pin depth is positive (protrusion), both mating
connectors will almost certainly be damaged.
Also, if the male pin diameter is greater than the maximum
3.5 mm specification, it will cause permanent damage to
the female receptacle. If you try to measure the pin depth
and the gage will not fit over the pin, it is an immediate
indication that the pin is too large and must not be
connected to the precision adapters. The male pin of the
DUT connector may fit into the gage and give a correct
measurement, but still be slightly too large for the
precision adapter female receptacle.
Repair and Replacement
In general, bent or deformed parts cannot be repaired in
the field. It is necessary to return the part to an HP service
center for repair or replacement. The air line center and
outer conductors must be replaced as a set. Refer to the
replaceable parts chapter in the service manual supplied
with the calibration kit for replacement part numbers and
ordering information.
