| A-scan Memory | 500 trace patterns can be stored which can be recalled, printed, or transferred to PC via USB (with NOTE/DETAIL). Unlimited No of A-scan can be directly stored in USB disk with auto file naming. |
| B-scan Memory | 50 B-scan can be stored (with NOTE/DETAIL) which can be recalled, or transferred to PC via USB. Unlimited no of B-scan can be directly stored in USB disk with auto file naming. |
| Calibration Set-up | 50 different calibration set-ups can be stored and recalled. |
| T-LOG | 20000 readings can be stored in 20 different files. Five different types of file templates for file creation. Stored readings can be transferred to PC via USB. |
| DAC | Dynamic DAC curve can be digitally plotted (smooth parabolic curve) on screen with selectable additional offset curves from 0 to 14 dB in 0.1dB selectable steps. DAC curve can be set as a flow monitor gate. DAC can be plotted using minimum 2 to maximum 10 points. |
| TCG | After plotting DAC , TCG( Time corrected Gain) can be activated. This brings All echo signals to equal height irrespective of depth. |
| AWS | Built-in Software for evaluation of defect in accordance with AWS standard. |
| DGS | Defect size evaluation based on 18 predefined probe data and one custom Probe set-up per memory location. Defect size is directly displayed in ERS Value(Equivalent Reflector Size). |
| Digital Readout | Thickness/Depth can be displayed in digital readout when using a normal probe and sound path, Surface Distance and depth of echo signals of GATEa /GATEb are directly displayed when angle probe is in use. Measurement point can be selected to be peak or flank. Echo height, ERS value, dB diff of DAC/DGS curve to signal height, Echo height respect to DAC in terms of percentage or in dB can be measured, T-minimum, Travel-distance can be measured when encoder is connected and time of travel during Freerun B-scan . |
| Measurement Unit | Metric or British unit of measurement is selectable. |
| Software | dVaSoft Interface software for transferring A-scan / B-scan/ T-LOG from da Vinci to PC is supplied with da Vinci delta. |
| Printer | USB printer (PCL3 compatible) can be directly attached to da Vinci delta for Attachment printing of stored A-scan waveform with calibration data and note detail. |
| Display | High brightness active matrix colour TFT LCD display. Display area 320×240 Pixel (117×88mm). Five different colours and Grid scheme options. colour leg facility for angle probe for easy interpretation of skip distance. |
| Full Screen | By pressing enter key for a few seconds A-scan will be displayed in Full screen area. |
| Reference A-Scan | Reference A-Scan pattern of standard test object can be saved and recalled in background for easy comparison during testing. |
| Video Output | VGA video signal output for monitor/projector connection. |
| PRF | 4Hz TO 500Hz. Selection in 10 scalable steps. PRF can go down up to 4Hz When PRF is selected to 1 and maximum achievable coupled to range when PRF is selected to 10. |
