KEY FEATURES
SYFD650C Portable Ultrasonic Flaw Detector with hi-resolution color TFT LCD display.
The background color and the wave color can be selectable according to the environment. LCD brightness can be manually set. Continue working over 8 hours with high performance lithium-ion battery module (with large capacity lithium-ion battery option), easy to be dismantled and the battery module can be charged independently offline. It is light and portable, easily to be taken by one hand; easy operation; superior reliability makes it long life.
 
RANGE
0~ 9999mm (at steel velocity); range selectable in fixed steps or continuously variable.
 
PULSER
Spike excitation with low, middle and high choices of the pulse energy. 
Pulse Repetition Rate: manually adjustable from 10 to 1000 Hz.
Pulse width: Adjustable in a certain range to match different probes.
Damping: 200Ω, 300Ω, 400Ω, 500Ω, 600Ωselectable to meet different resolution and sensitivity need.
Probe work mode: Single element, dual element and through transmission;
 
RECEIVER
Real-time sampling at 160MHz high speed enough to record the defect information.
Rectification: Positive half wave, negative halfwave, full wave, and RF  
DB Step: 0dB, 0.1 dB, 2dB, 6dB step value as well as auto-gain mode
 
ALARM
Alarm with sound and light,.
 
MERMORY  
Total 100 configuration channels store all instrument operating parameters plus DAC/AVG curve; stored configuration data can be easily previewed and recalled for quick, repeatable instrument setup. Total 1000 datasets store all instrument operating parameters plus A-scan. All the configuration channels and datasets can be transferred to PC via USB port.


FUNCTIONS  
1. Peak Hold: Automatically searching the peak wave inside the gate and hold it on the display.
2. Equivalent diameter calculation: find out the peak echo and calculate its equivalent diameter.
3. Continuous Record: Record the display continuously and save it to the memory inside the instrument.
4. Defect Localization: Localize the defect position, including the distance, the depth and its plane projection distance.
5. Defect Sizing: calculate the defect size
6. Defect Evaluation: Evaluate the defect by echo envelope.
7. DAC: Distance Amplitude Correction
8. AVG: Distance Gain Size curve function
9. Crack measure: Measure and calculate the crack depth
10. B-SCAN: Display the cross-section of the test block.

REAL-TIME CLOCK
Real time clock for tracking the time.
