The pin depth value of each calibration device in the kit is not specified, but is an
important mechanical parameter. The electrical performance of the device depends, to
some extent, on its pin depth. The electrical specifications for each device in the kit take
into account the effect of pin depth on the device's performance.
pin depths and measurement uncertainties, and provides observed pin depth limits for the
devices in the kit. If the pin depth of a device does not measure within the observed pin
depth limits, it may be an indication that the device fails to meet electrical specifications.
Refer to Figure 2-1 for a visual representation of proper pin depth (slightly recessed).

a. Approximately +2 sigma to −2 sigma of gage uncertainty based on studies done at the
factory according to recommended procedures.
b. Observed pin depth limits are the range of observation limits seen on the gage reading due
to measurement uncertainty. The depth could still be within specifications.
NOTE When measuring pin depth, the measured value (resultant average of three
or more measurements) is not the true value. Always compare the measured
value with the observed pin depth limits in
condition of device connectors.
