Troxler 3440 - Set Units

6–22
PRECISION
Test results with precision limits as low as 0.5 pcf (8 kg/m
3
) are possible
under certain conditions. When given the desired degree of precision and a
test measurement, the 3440 automatically supplies this precision data to the
operator. Assuming the precision requested is within range and the time
required to calculate the required result does not exceed 60 minutes, the
following procedure can usually produce the required results.
The operator should be certain that the gauge is in the correct mode: Soil or
Asphalt. To execute the Precision function, press 〈SHIFT〉 and
〈SPECIAL〉 for:
Press 〈YES〉 two times for the display:
Press 〈8〉 for the display:
If the gauge is in Soil mode, the display will request that the gauge be set
for the correct depth and will instruct you to press
〈START/ENTER〉.
If the gauge is in Asphalt mode, the display will reflect that the gauge
should be in the backscatter position.
