Gaging Connectors
When making a measurement, the gage dial indicator will travel in one of two 
directions. If the center conductor is recessed from the zero reference plane, 
the indicator will move counterclockwise to determine the amount of 
recession, which is read as a negative value. If center conductor protrudes, the 
indicator will move clockwise to measure the amount of protrusion, which is 
read as a positive value. Refer to “Typical Pin Depth Values” on page 5-21 for 
definitions of protrusion and recession.
