Model 3451 6–5
MOISTURE OFFSET
The moisture offset ( k ) is determined by comparing the true
moisture of a laboratory sample with the gauge moisture reading.
The Model 3451 can derive the moisture offset either by taking a
moisture measurement and comparing the reading to the true
moisture entered by the operator, or by comparing measured and
true values entered by the operator. To access the moisture offset
functions, press the
〈
Moisture

button on the
Offset Menu
(see
Figure 6–1). The PDA displays the
Moisture Offset Select
screen shown in Figure 6–4.
New Moisture Offset from Gauge Reading
To derive the moisture offset by first taking a moisture reading, the
operator must take a reading with the gauge and enter the true
moisture derived by an oven dry or similar method. The gauge can
store one
partial offset , which allows the operator to take a reading
and enter the true moisture at different times.
NOTE
When using destructive methods such as drilling cores
or sample removal for true moisture measurement, take
gauge readings before removing samples.
