TAKING A REFERENCE READING
To ensure the accuracy of gauge measurements, Troxler
recommends that a reference reading be taken each time the gauge
is powered on, and periodically while taking measurements. A
reference reading consists of taking a density measurement on a
material of known density. The gauge then compares the reading to
the known value and uses the result of that comparison to adjust
future gauge readings.
NOTE
A reference standard, built into the gauge carrying case,
is provided for this purpose. Always take reference
readings using the reference standard in the carrying
case provided with the specific unit.
Turn the gauge on as described on page 2–4. At the Ready screen,
press the 〈REF〉 key. The gauge displays:
Place Gauge on
Reference Standard
(Carrying Case)
Press <START>
Place the gauge on the reference standard (in the carrying case).
Ensure that the circular sensor on the bottom of the gauge is
centered between the four locating pins inside the case, and that the
sensor rests flat against the surface.
Press the 〈ENTER/START〉 key to begin the reference reading.
Upon completion, the gauge displays:
Reference Reading
Complete
Press <ENTER>
Press the 〈ENTER/START〉 key to continue. The gauge stores the
result of the reading and returns to the Ready screen. The result is
then used to adjust all gauge readings.
