1. Density - allows the addition or subtraction of a given
quantity from the wet density (WD) readings measured
by the gauge. This function can be used for correction
of the gauge readings to other test methods, such as
asphalt cores tested by water displacement method.
2. Moisture - corrects the gauge moisture readings to oven
or speedy dry moisture.
3. Trench - corrects for the effect of trench walls to gauge
moisture readings.
To use the offset mode:
1. Press the MENU button.
2. Select the 2 button.
3. Scroll UP or DOWN to the offset you want to enable.
4. For entering a negative number use the DOWN button,
for a positive number use the UP button.
Density Offset - use this function to offset the density up or down
by a known quantity. For example, if the gauge’s wet density
(WD) is 142.0 PCF and the actual field density is 145.0 PCF, use a
density offset of 3.0 to correct the gauge readings. The offset
value can be positive or negative. The UP key is for the (+) sign
and the DOWN key is for the (-) sign. Follow gauge prompts to
enter this value.
Note: When density offset is enabled a Y on the gauge ready
screen will appear next to offset.
Moisture Offset - This function provides a means for correction of
gauge moisture results to results obtained by oven dry, speedy
