which a set of independent measures is launched, which can be stopped by the operator. 

SAVE:  enables/disables  the  automatic  save  of  the  measures.  As  already  mentioned  above,  the  tester

saves every set of measures when the single mode is activated, while only one value per any set of three
consistent measures is saved when the continuous mode is used. Moreover, in this case, the measure is
connected with an identification character that matches the measure to a “test”. Anytime a continuous test
begins, this character is increased.

GAIN: it adjusts the intensity of the ultrasonic impulse according to four different values (250V, 500V, 750V,

1000V)

LANGUAGE: it sets the active language by selecting it among the available ones (Italian, English, French,

German, Spanish)

SAMPLE: it sets the length (in units of time) of the sample to be used for the calibration.

CALIBRATION: it starts the calibration process hereunder described. It is activated by pressing the F1 key

until the cursor places itself on the writing provided and then by pressing F2.

The F4 key brings back to the main screen. 

2.06  CALIBRATION 

By  selecting  the  appropriate  entry  of  the  configuration  menu  and  by  pressing  the  F2  key,  it  is  possible  to 
perform a two-points calibration in order to achieve the highest possible level of precision on the performed 
measures. 

By starting the calibration, the following screen appears: 

START CALIBRATION 

EXIT 

This  screen  suggests  the  operator  should  bring  the  probes  in  contact  to  measure  the  “zero”  point  of  the 
tester.  In  order  to  achieve  a  better  mechanical  contact  between  the  probes,  it  is  necessary  to  sprinkle  the 
contact surfaces with the appropriate product provided with the kit. Afterwards, press the F1 key to start the 
reading or the F4 key to cancel the calibration. 
As by a normal measure, the main screen will be displayed and the zero value which has been measured is 
superimposed on it. In order to validate the measure, press the F1 key after that the reading has stabilized.

 

Afterwards the following screen is displayed:

 

START CALIBRATION 

EXIT

 

This  screen  suggests  the  operator  should  put  the  cylindrical  sample  (provided  with  the  kit)  between  the 
probes  in  order  to  measure  the  second  point  of  the  characteristic  curve.  In  order  to  obtain  a  better
