Measuring procedure
The measurement can be performed once all necessary settings have
been made.
3.3.1
Reflector search
To start the search mode, press and hold down the search button
(compare Fig. 9 MIT-SCAN-T3 design, (7), p. 14). The signals of the
four sensors are pictured in display as four separate bars (s. Fig. 25 on
next page).
The higher the bar, the stronger the received signal. The bar amplitude
depends on the size of the reflector and its distance from the probe.
Reflector searching procedure:
Sweep probe over road surface in wide side-to-side motions
Observe the four search bars
When bar amplitudes or a vibration indicate detection, perform
shorter sweeping motions for more exact localization
Determine reflector center and put down the probe
