8.2 Calibration Modes
The EPOCH 6LT features multiple calibration modes to accurately meet the
requirements of the selected transducer, calibration test block, and application. These
calibration modes can be set in the calibration dialog box. There are two modes for
straight beam transducers and two modes for angle beam transducers.
8.2.1 Straight Beam Modes
Straight beam calibrations can be performed using one of two modes. For the
purposes of the EPOCH 6LT calibration, straight beam refers to all zero-degree probes,
including contact, dual, delay line, immersion, etc. The two straight beam calibration
modes are as follows:
• Thickness
This standard straight beam calibration mode requires you to provide two
different, known material thicknesses to properly calibrate the instrument. The
