DIAL INDICATOR
The static port measurements are obtained at four locations on each static port as shown in
Figure 8-6. These measurements are used to find an AVERAGE and ANGLE for each of the
four static ports. The AVERAGE is calculated by adding the four measurements and dividing
the total by 4. The ANGLE is calculated by subtracting the minimum measurement from the
maximum measurement. The calculated AVERAGE and ANGLE for each static port must fall
within the ranges shown in Figure 8-7.
Perform the static port measurement as follows:
1. Wipe the surface of static ports clean with isopropyl alcohol.
2. Place the gauging assembly onto the static port surface as shown in Figure 8-5.

The dial indicator shows 0.100 inch when completely flush. Therefore, subtract
the readings from 0.100 inch to determine the actual static port height. This
should be completed before making any calculations.
3. For each static port, measure the static port height at the A, B, C and D locations as
shown in Figure 8-6. Record the measurements in the measurement log, Figure 8-7.
