Learn Mattel ultrasonic flaw MUT600B several Significance probe noun 1, the ultrasound probe is used to match the probe damping, by adjusting the damping to suit the acoustic impedance of the test material, thereby improving the display of the echo amplitude, width and resolution. 2, the pulse amplitude of the pulse amplitude is the voltage amplitude of the transmitted pulse signal. Mattel MUT600B ultrasonic flaw detector pulse amplitude is fixed at 500V. Within the instrument, ultrasonic transmitter circuit generates electrical pulses delivered to greatly ultrasound probe, excitation probes emit ultrasonic pulses incident on the material to be seized. Transmit pulse amplitude (pulse voltage) and duration (pulse width) determines the size of the emission intensity (also known as the transmission power, emission energy) of the size of 3, the pulse width of the pulse width is the time duration of the firing pulse values ??indicated. By adjusting the value of the pulse width can match probes of different frequencies. This parameter μs (microseconds) as a unit laser flaw detector, the adjustment in the range of (0.1 ~ 0.513) μs. When the probe frequency of 2.5MHz, pulse width range of options is recommended (0.1 ~ 0.2) μs. The lower the frequency of the probe, you can choose a larger pulse width. Resolution pulse width too much effect, in the near-surface resolution demanding circumstances, not to use too large pulse width and pulse amplitude. Of course, the emission intensity, bringing high sensitivity, penetration distance, penetration of the benefits, it is necessary to take into account the resolution requirements and specific circumstances of the subject material (such as sound attenuation size) for comprehensive consideration. Mattel ultrasonic flaw detector MUT600B pulse width fixed 0.2μs. 4, the repetition frequency to generate ultrasonic waves per second pulse from the pulse generator excitation frequency wafer probe called (the ultrasound transmitter) repetition frequency. This parameter is used to set the instrument ultrasound system transmit repetition frequency (PRF). When testing the workpiece scanning speed, the need to use a high repetition frequency magnetic detectors is to prevent defects missed; when scanning is slow, set a lower transmit power instrument repetition rate can be reduced. If the detection range is large, for example greater than 2000mm, the recommendations do not transmit the repetition frequency greater than 100Hz. Mattel ultrasonic flaw detector system information to set the system date and time is set to enter the date and time settings screen (Settings → information), select the year - month - day project, and the key or click the knob, the year parameter is underlined, indicating that the parameter into the change state rail flaw detector, as shown in FIG. Rotate the knob to adjust the year argument, after adjustment is completed key or click the knob to enter the parameter adjustment month. Adjusted by the same method of operation, month, day parameters, and finally click on the button or knob completion date set. Similar time setting method. System information display instrument software version number and serial number. The parameters are read only flaw, a user can not change. Restore Factory Settings Restore factory operating for formatting the instrument memory, the operation will be all channels, waveform and videos are clear and instrumentation system restores all parameters to the instrument factory state. When the instrument parameters confusion, abnormal working when the instrument can be initialized by the operation. During initialization Do not make any key operation, and do not shut down. Restore Factory Operation: Select Storage → clearing → restore factory, and then click on the button or knob operation.
