Using electrical tape, secure witness plate in place.
Figure 3. Attach parachute riser to device.
Figure 4. Upon completion of drop, remove witness plate from device.
Figures 5 & 6. Measure the combined height of the ball and the witness plate to determine the depth of the indentation on witness plate. Convert the measurement to load with the calibration chart and the calibration strip to obtain test results
