Gate Alarm – Gate position, gate width and gate height can be adjustable at will. The B gate can chose to set wave-getting alarm or wave-losing alarm. The beep in gate and LED light can be alarmed or closed (the LED light alarm is very effective under the noise environment).
Data Storage – The instrument is built with mass storage, the data and files will not be lost because of instrument power breakdown. The storage contents included channel parameters, waveform pictures and video files. It supports 100 groups of flaw detecting parameters channels. It can preset well for the combination parameters of various types of probes and instruments as well as set testing standards for each industry freely. It can save 1000 pictures of detecting echo signals and parameters. It can realize to save, read and transfer the data via the USB port.
Video Function – The instrument supports for saving the inspection process as video file and save it to the internal storage card. Video file can be replayed through the instrument. The instrument can support 2 minutes video.
REAL-TIME CLOCK – Record and save the tracking record of detecting date and time in real time.
Communication – With USB2.0 high speed communication interface, it also can use special software to upload and download data through the USB port.
Battery Module – The large capacity lithium battery module is easy to be assembled and disassembled. It can be charged independently but also charged by inserting wire. Its continuously working time is more than 8 hours.

Flaw Detecting Function:
Flaw Detecting Standard: Built-in the commonly used flaw detecting standards for each industry. It
can be directly called for using convenient and fast.
Welding Figure: It can set the weld parameters, show the welding figure and defects as well as echo
path directly during testing.
Automatic Calibration: Automatic calibration for P-Delay and probe angle (K value), automatic
measuring function for sound velocity.
Peak Memory: real-time search the defect with highest wave and record the defect peak echo.
Defect Positioning: real-time display the defect level, depth (vertical) and sound path position.
Defect quantify: real-time display the defect equivalent dB value
Defect quality: With echo envelope waveform, it is convenient for judging according to artificial
Curved Surface Correction: Used for flaw detecting for the curved surface workpiece, it can display
the defect circumferential position and depth in real time.
Digital-analogy dual-use: without needing do AVG curve, using the bottom wave gain method to
measure dB value to achieve the dual-use for digital-analogy, it is easy to operate.
ΦValue Calculation: It can auto-calculate and display the defects equivalent size after finding the
peak echo of defect when the straight probe detecting to the forgings.
DAC/AVG: Automatic produced curves without limitation for sampling point, it can do offset and
correction for the curves. The curves float automatic with the gain and expand automatic with sound
path as well as move automatic with time delay. It can show any aperture AVG curve.
Gain: 0 dB to 110 dB adjustable in selectable steps 0.1 dB, 1 dB, 2dB and 6dB. Unique automatic
gain adjustment and scanning gain function make the flaw detecting fast and accurate.
AWS D1.1/1.5: The American Welding Society standard provides a dynamic reflector “defect level”
for all types AWS weld inspection applications. It can avoid manual calculation and improve the
Crack Depth: with endpoint diffraction wave, it can measure and calculate the crack depth
Envelope in Gate: Amplify the echo details, easy for echo analysis.
Continuous Record: real-time record the waveform, save and playback it.
Waveform freeze: freeze the waveform showed on the screen for conveniently analysis the defect.
Echo Code: Display 1-6 times echo display area in different colors, distinguish the first and second
wave better, easy to determine the defect position.
Common B Scan: real-time scanning, cross section display,make the detecting result more visually.
