When taking counts on thin layer asphalt, Troxler recommends
averaging large numbers of readings over the same material to
ensure results that are more accurate. Use at least ten (10) gauge
readings before cutting cores. Enter the number of measurements
the gauge is to average, and press the
〈
ENTER
〉
key.
With the source rod in the backscatter position, begin the
measurement by pressing the
〈
START
〉
key. The gauge displays the
progress.
After taking the reading, the gauge displays the results and prompts
the operator to accept or reject the results. If the operator rejects the
results, the gauge retakes the measurement. If the operator accepts
the results, the gauge continues to the next measurement.
Reposition the gauge and repeat the above procedure for each count
(see Figure 6–2). After taking all the readings, the gauge displays:
