А1040 MIRA Low-Frequency Ultrasonic TomographOperation Manual40ACOUSTICCONTROLSYSTEMSPROPERUSE22.1 OPERATING RESTRICTIONSThe device is intended for operating conditions listed in the Section 1.1.22.2 PREPARING FOR OPERATION2.2.1 Possible use of the tomographThere are two possibilities of inspection of objects using the tomograph: local and continuous testing.2.2.1.1 Local testingWhen performing the local testing mode, the device is placed in any place on the surface of the inspected object. Here itis possible to analyse the internal structure and the cross section in a specific place. Based on the results it is possible at onceto receive the necessary information or to choose a direction where it is better to move the device to receive a more completeinformation.2.2.1.2 Continuous testingContinuous testing is made step-by-step by moving the device continuously with further imaging and saving of the results.The direction of movement and the displacement step of the device is defined earlier and does not vary in a testing current,regardless the images received on the screen.The continuous testing is used for complete inspection of the area of the tested object, with further modeling of the internalstructure and saving the data, if necessary. The continuous testing is a long procedure which needs the tested object to bemarked with a pattern before starting the testing. In order to check the working capacity of the device, it is highly recommendedto test the instrument in the local testing mode.2.2.2 Setting proceduresThe tomograph is delivered ready for operation, not further adjustments are needed.Before starting the work, please charge the battery.
