2.3 USING THE INSTRUMENT
2.3.1 Working with the instrument
During the inspection the temperature dependence between the ultrasonic propagation velocity in cooled or heated mate-
rials shall be considered. For the best measurement results the instrument must be adjusted to the ultrasonic velocity by the
calibration sample with the same temperature as the temperature of the inspected object.
2.3.2 SETUP mode
The SETUP mode includes a list of the editable parameters, EMAT testing
procedures and procedure of velocity calibration with the sample, transfer of
the data to PC, viewing the library of the transducer and operation with the
library of materials.
All settings of the instrument will be saved after it is switched Off or the
accumulator goes dead.
The screen in the SETUP mode is shown in the Figure 18.
The active keys in any of the menus of the SETUP mode:
-scrolling the active line through the menu options, tran-
sition is carried out cyclically in both directions. The parameter highlighted by
the active line becomes available for selection or editing;
- decrease/increase the digital value of the selected pa-
rameter.
The menu options of the SETUP mode are common for all measurement
modes, their corresponding parameters (in the metric measurement system)
and functions are shown in the Table 4.
