2.3 USING THE DEVICE
2.3.1 Work with the device
It is not recommended to slide the operating surface of the PET along the surface of the tested object, if it is not necessary.
If you have to inspect the TO in several points and the tested object has a large surface, please lift the transducer and put it on
the required points. Do not continuously scan the whole surface. Scanning accelerates the wear of the PET significantly. If it is
necessary to perform the scanning, for example to determine the local material thinning, please perform it with outmost care
without big pressure on the PET. Use only clean contact liquid and clean the surface from dirt prior to perform the scanning.
During the testing process please consider that the ultrasonic propagation velocity depends on the temperature of the
tested material and differs in cold and warm objects.
To achieve the most accurate measurements, please set the device considering the ultrasonic velocity of the sample
with the same temperature as the object to be tested.
It is recommended to remove all contact liquid from the ultrasonic transducer after finishing the work. A drop of liquid
can lead to the reflected signal. The device will not be able to switch off automatically.
2.3.2 SETUP mode
In the SETUP mode you can perform the PT testing procedure, calibrate the velocity using the sample with a definite
thickness, view the transducer library, work with the list if materials and view the list of parameters accessible to editing.
All device settings are saved when you switch off the device or when the battery is completely discharged.
The SETUP mode of the screen is shown on the Figure 16.
The following keys are active in any menu of the SETUP mode:
-
Moving up and down the menu items, the movement is done cyclically in both directions. The parameter
in the active line can be selected and edited;
- Selecting the category of numerical value for editing;
- Reducing or increasing the numerical value of the selected parameter.
