Reading the Connector Gage

The gage dial is divided into increments of 0.0001 inch and major divisions of 0.001 inch (see Figure
3-2). For each revolution of the large dial, the smaller dial indicates a change of 0.01 inch. Use the
small dial as the indicator of multiples of 0.01 inch. In most connector measuring applications, this
value will be zero.
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 indicate the amount of recession, which is read as a negative value. If the center conductor
protrudes, the indicator will move clockwise to indicate the amount of protrusion, which is read as
a positive value. Refer to "Pin Depth" on page 2-3 for definitions of protrusion and recession.
