THIN LAYER SPECIAL CALIBRATION
The Thin Lift Special Calibration function allows the operator to re-
calibrate the gauge for materials not covered by the factory
calibration.
The thin layer special calibration uses the average of 3 to 20
measurements. Troxler recommends averaging one-minute readings
taken on a test site (see Figure 6–14 on page 6–16) or around a core
site (as shown in Figure 6–20). This average and the density
obtained by another method (such as core samples) are used to re-
calculate the gauge constants.
To access the Thin Lift Special Calibration function, press the
