Ultrasonic Flaw Detector A1211 Mini ACOUSTIC CONTROL SYSTEMS 1.3 INSTRUMENT DESIGN AND OPERATION 1.3.1 Instrument design The instrument includes an electronic unit (Figure 1), to which changeable piezoelectric transducers are connected via cables. In the upper part of the front panel a TFT display is situated, it displays the measurement results and service information, necessary for using the instrument. The display provides full visual control of the measurement process with colored indication. Under the display a film keyboard is located used to control the instrument. On the upper side...

ACOUSTIC CONTROL SYSTEMS Ultrasonic Flaw Detector A1211 Mini While working with the echo-method with a single crystal or a dual search transducer the temporary position of the echo-signal on the screen is in proportion to the distance from the reflector to the transducer. 1.3.3 Operating modes The main operating mode is the FLAW DETECTOR mode, additional STOP and SETTINGS modes are present. In the operating mode the emission pulse is formed, the measurements are made, the received echo-signal is amplified and displayed on the screen. The STOP mode is used for freezing the signal realization...

ACOUSTIC CONTROL SYSTEMS Ultrasonic Flaw Detector A1211 Mini The keyboard of the instrument (Figure 8) has 11 functional keys and an on/off key. Main functions of the keys: The key (ON / OFF) is used for turning the instrument on/off. NOTE: THE INSTRUMENT AUTOMATICALLY TURNS OFF AFTER 10 MINUTES WHEN NO KEY IS PRESSED AND NO MEASURING IS PERFORMED! NOTE: AFTER 2 MINUTES THE ILLUMINATION OF THE SCREEN IS AUTOMATICALLY SET TO THE MINIMAL VALUE 20% IF NO KEY IS PRESSED AND NO MEASURING IS PERFORMED! The functional keys (F) are used for different operations depending on the selected mode of the...

Ultrasonic Flaw Detector A1211 Mini ACOUSTIC CONTROL SYSTEMS 2.1 OPERATIONAL LIMITATIONS The instrument is designed for operation under environmental conditions specified in the section 1.1.2. 2.2 PREPARING THE INSTRUMENT FOR USE 2.2.1 Preparation of the surface The surface of the tested object should be cleaned from dirt and sand, if it is covered with corrosion, then remove the loose rust and apply more contact liquid on the smooth surface. Cleaning rough corroded surfaces improves the measurement certainty and provides a longer service life of the transducer. 2.2.2 Connecting the...

ACOUSTIC CONTROL SYSTEMS Ultrasonic Flaw Detector A1211 Mini 2.2.3 Switching the instrument ON/OFF To turn the instrument on the key should be pressed. At the moment of turning on a short tuneful signal will ring. On the display of the instrument the main screen is shown for 2 seconds with the name of instrument and version of the firmware (Figure 11). The instrument will automatically enter the mode, which was set at the moment of the last switching off, with corresponding settings. Turning the instrument off is done by pushing the key or automatically after 10 minutes when no key is...
