Measurement Modes:

Mode 1: Signal Monitor

Mode 2: Depth and amplitude of first signal in gate.

Mode 3: Echo-to-Echo distance measurement. (single gate)

Mode 5: T-Min mode for holding minimum thickness reading.

Resolution: 0.01mm (0.001in) for distance measurement or 1% FSH for amplitude
measurement. Large display of measurement at the top of A-Scan display. Measurement mode selectable between peak and flank.

A-Scan Memory: Maximum of 800 waveforms can be printed or transferred to
a PC using optional SDMS software.

Panel Memory: 100 stores for retaining calibrations.

Thickness Logging: Storage for 8000 thickness readings configured either by Block/Location/Number mode or pre-programmable work sheets in sequential mode. Readings can be exported to MS Excel using optional SDMS software.

DAC: DAC defined by up to 10 points and digitally drawn on screen. DAC curves meet requirements of EN 1714, JIS and ASME standards, selectable between -2, -6, -10, -12 and -14dB. Amplitude read out selectable between % DAC or relative dB.
