USING THE GAU

NOTE
If the reference reading is out of range and the gauge
displays an error message, check the following:
♦
Ensure that the circular sensor cover is firmly in
place on the gauge sensor (press firmly around the
perimeter of the cover).
♦
Ensure that the cover and reference standard are
totally clean and free of any asphalt residue,
moisture, or debris. Clean with WD-40 or other
suitable means.
♦
Ensure that the sensor cover is seated flat and flush
on the reference standard, within the four locating
pins, with the gauge in the case.
Repeat the reference reading. If the reference reading
still does not pass, contact Troxler technical support (see
page A–10).
To verify that the gauge is still accurate during use,
perform the following check:
♦
Ensure that the gauge is turned on and in
measurement mode.
♦
Turn off (disable) all operator-installed density
offsets and mix calibrations. See Chapter 3 for
specifics.
♦
Place the gauge on the reference standard and verify
that it reads within
±
0.5 pcf (
±
8 kg/m
3
) of the actual
density value stamped on the reference standard. If
the reading is outside these limits, take a reference
reading as described in this section to adjust the
gauge.
Note that each reference standard is unique to that
individual gauge. Use care to not intermix different
gauges and cases.
