dry or other laboratory drying methods. Use the following
equation to calculate the correction and enter this value into
the gauge when prompted by the software.
Where %M (Gauge) is the gauge derived % Moisture (%M)
value with K=0 (no moisture offset, factory calibration) and %M
(True) is % Moisture determined by oven dry, speedy dry or
other laboratory methods.
Once the K value is entered in the gauge, all subsequent test
results for moisture will be corrected by this offset. Use the UP
key for (+) sign and the DOWN key to enter (-) sign.
Note: When moisture offset is enabled a Y on the gauge ready
screen will appear next to offset.
Trench Offset - This function provides a means for correction of
wall influence on gauge moisture counts. Use this offset
function when taking measurements in a trench with walls 1
meter (3 ft.) or less from the gauge.
To use this function, take a standard count on the reference
standard block outside the trench and record the moisture
standard count, MS. Place the gauge on the standard block in
the center of the trench with the handle parallel to the wall in
SAFE position. Then press START. The gauge will automatically
calculate the Trench Offset by the equation
Trench Offset= MS – M Count
