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)

Resolution: To 0.01mm (0.001in) for distance measurement or 1% FSH for amplitude measurement. Large display of measurement at 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.

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, % FSH or relative dB.

Auto-Cal: Provides automatic calibration from two echoes.

Clock: Sets time and date.

Reference Waveform: This menu displays a waveform from one of the A-log stores as a reference or fingerprint display in a colour different from the active display highlighting differences from the reference.

Notes: Alphanumeric labelling for panel and A-log allows the user to enter Notes for storage with panel settings and A-scans

Display Freeze: For capturing the current A-scan image.

Active Peak Memory: Envelope waveform for echo dynamic pattern determination, with simultaneous live A-scan display.

Keylock: Prevents accidental alteration of parameters.

Help Key: For instant operator guidance on using the Dryscan.

Language Support: Supports multiple languages. User selectable between English, German, Spanish, French, Dutch. Others available on request.

Waveform Smoothing: Gives a smooth signal envelope, simulating analogue equipment.

Outputs: Full bi-directional serial interface to transfer parameters, thickness readings and waveform memories. Composite video, PAL or NTSC compatibility. Analogue proportional outputs programmable to distance or amplitude of signal in the gate. Transmitter sync output.
