Thin Layer Special Calibration - Troxler Enhanced RoadReader Plus 3451 Manual Of Operation And Instruction

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
〈Special Calibration〉 button on the Change Settings menu
(see Figure 5–1). The PDA displays the Thin Lift Special
Calibration menu shown in Figure 6–21. The following sections
provide details on the Thin Lift Special Calibration function.
