To calibrate the probe zero setting push the button A it will appear on the LCD CALXX XX where xx xx is the calibration value If you are using the calibration block built on the unit select a velocity of 5920 m s and a calibra tion value of 5 0 mm Using a different calibration block with material velocity and thickness known select this values Use or buttons to increase or to reduce the calibration value of thickness Put some couplant on the calibration block Apply the probe on the calibration block Push shortly the ON button the LCD will display CALIBR gt WAIT gt DONE followed by the value of thickness measured in real time At this point the zero probe setting is calibrated If during the calibration the LCD will show ERROR for at least 3 second repeat again the cali bration starting from point 1 NOTE The calibration values of different probes can be stored in the unit Recalling a type of probe also the relevant calibration setting value will be recalled The calibration procedure have to be repeated every time it is used a new probe It is better any way repeat the calibration procedure every time you feel it is neces sary If you want avoid the calibration procedure press shortly the button 44 when you are at point 3 VISUALIZATION AND OR MODIFICATION OF VELOCITY VALUE Press shortly the button AN or W to show the actual velocity value setted Press ON shortly to go back to the measu
