System Linearity:Vertical = 0.5% Full Screen Height (FSH). Horizontal /- 0.2% Trace Full Screen Width (FSW).Reject (Selectable):Up to 80% Linear reject (removes baseline noise without affecting indication amplitude)
Or
Up to 50% Suppressive reject (increase zero offset and reduces amplitude of all echoes)
LED Warning when active.Units:Inch (in), Metric (mm) or microsecondsDisplay:Color Transflective VGA (640 x 480) TFT
Display area: 116.16 x 87.2 mm (4.57 x 3.43 in).
A-Scan Area: 400 x 510 pixels (normal), 460 x 620 (FS).
Colors: 9 color options with variable brightness.Gate Monitor:Two independent gates for measurement and monitoring. Start and width fully adjustable over the entire range of the instrument. Levels adjustable from 0% to 100%, positive or negative triggering on each gate with audible & visual alarms. Gate resolution is 5nS.Zoom:Expands range and delay to cover the area set by Gate 1 start & width controls.AGC:Automatic Gain Control automatically sets the signal in Gate 1 to a level between 10% and 90% FSH, tolerance between 5% and 20%.Measurement Modes:Mode 1:Signal monitor, Gate alarms can be active but no measurements are displayed.Mode 2:Depth and amplitude of first signal in gate.Mode 3:Echo-Echo distance measurements.Mode 4:Trigonometric display of beam-path, surface distance (including X-offset) and depth of indication from the inspection surface together with echo amplitude. Curved surface correction can be applied for convex and concave surfaces. Half-skip can be indicated on screen.Mode 5:Gate to Gate distance measurement.Mode 6:Flank to FlankMode 7:Beam Angle, calculated from beam path, hole radius and hole center depth.Measurement Display:Live display and updates on screen at 3 times per second. Large display of a single measurement available.Contour:Trailing-Edge slew-rate control to reduce half cycles in rectified modes. Selectable from one of 6 levels.Waveform Smoothing:Select from:

1. None (both min and max values are displayed in the A-Scan)
2. Fill (Min values set to baseline value, produces a solid A-Scan)
3. Smooth (Min values ignored, produces a clear outline A-Scan)

Persistence:Causes previous A-scans to “fade out” at a user-determined rate.Auto-Cal:Provides automatic calculation of velocity and probe zero from 2 reference echoes.Reference Waveform:Displays a previously stored A-log in a color different from the active display: enabling a quick visual check of the differences.Clock:Built in, battery-backed RTC keeps time and date. Visible on the status line, always stored with Panels, A-logs etc.Internal Memory:4 GB storage available for A-scans, panels, T-logs, B-logs etc. 450,000 Panels, 200,000 A-Logs, 300,000 B Charts, 440,000 T-Logs.Active Peak Memory:Retains all A-scans on screen for echo-dynamic pattern analysis, with the active A-scan displayed in a separate color.Notes:Alphanumeric labelling for panel stores, A-logs, B-logs etc.Display Freeze:Hold the current waveform on screen for off-line processing.Language Support:Multiple languages are selectable from a list including:
