DIAGNOSTICS MENU
The RoadReader Plus software includes a
Diagnostics Menu
(see
Figure C–1) that enables the operator to perform a stat test and a
drift test, as well as to calibrate the source rod depth strip. To access
these functions, press the
〈
Gauge Tools
〉
button on the
RoadReader Plus main menu (see Figure 3–11). The software
displays the
Gauge Tools
menu shown in Figure 3–17. Press
〈
Diagnostics
〉
to display the
Diagnostics Menu
.
STAT TEST
Erratic readings, or readings that seem to fluctuate, may indicate a
problem with the gauge. If the readings are suspect, perform a
stat
test
, or statistical stability test, to validate the normal operation of
the gauge.
A stat test consists of 20 one-minute counts. From the 20 counts, the
gauge calculates the standard deviation, which is compared to a
theoretical standard deviation value. Ideally, this ratio should be
0.354, with acceptable limits from 0.225 to 0.465. The gauge is
considered
unstable
if the ratio is outside these limits and the stat
test will fail. If the stat test fails, ensure that the gauge setup and
testing was conducted correctly, and take an additional test. If the
second test fails, contact the nearest Troxler service center.
To access the
Stat Test
function, press
〈
STAT Test
〉
on the
Diagnostics Menu. The PDA displays the
STAT Test Menu
(see
Figure C–2).
Taking a Stat Test
Choose an area free of other nuclear gauges or radioactive sources.
Place the gauge on the reference standard block as shown in Figure
4–2 on page 4–3.
To perform a stat test, press
〈
Take STAT Test
〉
. The PDA displays
To take a STAT test, place the gauge on the standard
block with the source rod in the STD position and click
OK.
Ensure that the gauge is properly positioned and press
