Function & applicationThe instrument can be widely used in locating and sizing hidden cracks, voids, disbands and similar discontinuities in welds, forgings, billets, axles, shafts, tanks, pressure vessels, turbines and structural components.
Working PrincipleWhen presence of a defect in a workpiece with homogenous material, due to the defects, it will inform the interface among different mediums between the defect and workpiece. As the acoustic resistance is different at the interface, after the pulsing ultrasonic wave met the interface, it will produce reflection. The reflected energy will be received by the probe. Then it will show a reflection waveform in a certain abscissa position in the display screen which is the defect depth in the workpiece. The height and shape of reflecting wave would be different caused by the different defects which reflect the defect’s character.
Working ConditionsOperating Temperature: -10℃ to 50℃;
Storage Temperature：-30℃ to 50℃
Relative Humidity: (20 ~ 95)% RH
The surrounding environment should avoid of vibrating, strong magentic field, corrosive medium and heavy dust.
Instrument FeaturesGate 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).
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 1000 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 10000 pictures of detecting echo signals and parameters. It can realize to save, read and transfer the data via the USB port.
The instrument supports for saving the inspection process as video file and save them to the internal storage card. Video file can be replayed through the instrument but also can be uploaded to the computer for replaying through special software.
Support maximum 100 pieces of video files, the video totally time is about 15 hours. Playback the inspection process video makes great convenience for learning detecting but also saved for the future analysis to the inspecting process.
Record and save the tracking record of detecting date and time in real time.
High speed USB2.0 communication interface support U disk mode and data connection mode. Invent the instrument internal memory card as U disk, it can make backup for the data to PC conveniently. It also can use specialty software for upload and download the data via USD port.
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.
Operating Method and Attentions
Simple Operation Way:
1. Connect the probe to instrument with probe cable
2. Power on the instrument
3. Choose the channel and clear the present channel
4. Calibration the probe
Straight Probe: P-Delay
Angle Probe: P-Delay, X-value, Angle
5. Make AVG curve (straight probe), DAC curve (angle probe)
6. Choose the function setting
7. Detecting flaw in the workpiece
8. Record the flaws
9. Power off the instrument after operation
1. During pressing key operation, please not be too hard. Please not use the hands with much oil or mud for operating the instrument keypad to avoid affecting the keypad working life.
2. Please clear the instrument cover after operation
3. Please keep the instrument in a dry and clean place
4. Please avoid oil, water or other liquids into the instrument and clean the instrument surface regularly.
5. Make sure not twist or press the probe cable, communication cable and power cable. Please grasp the plug root during inserting or pulling the cable. Don’t grasp the cable for pulling or inserting.
6. Please make sure the standard battery for working power adapter for charging. Otherwise, the instrument would be damaged easily.
1. Care of the Instrument
Clean the instrument and its accessories using a moist cloth. Only use the following recommended instrument cleaners: water, a mild household cleaner or alcohol (no methyl alcohol).
Do not use any methyl alcohol, solvents, or dye penetrated cleaners!
The plastic parts can be damaged or embrittled by these.
2. Care of the Batteries
Capacity and life of batteries mainly depend on the correct handling. Please therefore observe the tips below.
You should charge the batteries in the following cases:
Before the initial startup
After a storage time of 3 months or longer
After frequent partial discharge
The instrument requires basically no maintenance.
If the accident occurred during instrument using, the instrument will be abnormal which means the instrument will not be able to use. Please turn off the instrument connection with the battery by putting the battery switch to off. Then, power on the instrument again after waiting one minutes to see if it is back to normal.
We provide two year’s warranty and life-long maintenance to the instrument. Please kindly contact with our company or agent for instrument repair. Please don’t disassemble the instrument by yourself without our agreement.
