Rectification: full-wave, negative half-wave, positive half-wave and RF mode.
Reject: linear, 0 to 90 % screen height variable in steps of 1 %.
Monitor gates: 2 independent gates in color bar mode, start and width variable over the entire calibration range, response threshold of 5 to 95 % screen height variable in steps of 1 %.
Alarm: alarm signal via LED and connectable internal horn; alarm mode of positive logic, negative logic or DAC.
Zoom expands A-scan display area for increased screen resolution.
Magnify expands area within the selected gate over the entire display range for increased A-scan resolution.
Sound Path Measurement
Digital display of sound path (projection distance, depth) between initial pulse and the first echo in the gate, or between the echoes in the two gates, with selectable echo peak, echo flank or Japanese echo flank detection.
Amplitude Display
In % screen height: dB difference above gate height, dB difference above DAC or TCG, dB difference above DGS curve.
Displayed Reading
Sound path, (reduced) projection distance, depth, amplitude for every gate, user configurable at four positions of measurement line and of the zoomed display in the A-scan.
Display
5.7 inch LED backlight TFT-LCD.
Display resolution 320 x 240 pixels.
A-scan resolution 200 x 220 pixels, 320 x 220 pixels (zoom).
