4.1.5 Sensor Test
The PDP Sensor is calibrated at the factory. If the unit has not been operated in
some time, or you feel that it is not working properly, you can do a validation test.
The validation test ensures that the system is operating properly by measuring an
object with a known response. You will need the validation target supplied with the
system. The test will take approximately 5 minutes to complete. The sensor needs
to be set upside down on the asphalt. Ensure there are no objects within 1 meter
of the PDP Sensor and that nobody walks by the sensor during the test.
From the PDP main screen, press Tools, then press the Sensor Test tab. You will
see the screen in Figure 4-11.
Figure 4-11: Sensor validation test
Follow the directions on the screen for orientating the PDP sensor and the validation
target. These are illustrated in Figure 4-12, Figure 4-13 and Figure 4-14.
