New Special Calibration
To create a new special calibration, the operator must take readings
with the gauge and enter the true density. The Model 3451 can store
one partial calibration. A partial calibration allows the operator to
enter the true density or take readings at different times.

partial calibration exists, the PDA displays Place the gauge on
the measurement site, lower the gauge to the proper
depth, and click OK.
Place the gauge on the test site and position the source rod in the
desired measurement position.
NOTE
When using destructive methods (such as drilling cores
or sample removal) for true density measurement, take
gauge readings before removing samples. Position the
gauge over the designated test site as in Figure 6–14.
