А1040 MIRA Low-Frequency Ultrasonic Tomograph
2.1 OPERATING RESTRICTIONS
The device is intended for operating conditions listed in the Section 1. 1 .2
2.2 PREPARING FOR OPERATION
2.2.1 Possible use of the tomograph
There are two possibilities of inspection of objects using the tomograph: local and continuous testing.
2.2.1.1 Local testing
When performing the local testing mode, the device is placed in any place on the surface of the inspected object. Here it
is possible to analyse the internal structure and the cross section in a specific place. Based on the results it is possible at once
to receive the necessary information or to choose a direction where it is better to move the device to receive a more complete
information.
2.2.1.2 Continuous testing
Continuous 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 internal
structure and saving the data, if necessary. The continuous testing is a long procedure which needs the tested object to be
marked with a pattern before starting the testing. In order to check the working capacity of the device, it is highly recommended
to test the instrument in the local testing mode.
2.2.2 Setting procedures
The tomograph is delivered ready for operation, not further adjustments are needed.
Before starting the work, please charge the battery.
