6.
Rename the changed calibration by pressing the key «
» open the action menu with the
calibrations, highlight the "MOVE" item and confirm with the key «
».
7.
Enter a new calibration name. Moving the cursor on the virtual keyboard is done using the
keys «
» and «
», and confirm with key «
». To save a new name, you need
to move the cursor to the "SAVE" button and press the enter key «
».
2.3.5 Work in "INFORMATION" mode
In this mode, you can find data about the manufacturer. Also in the "INFORMATION" mode,
you can see the information about the device and the number of measurements. For this, using keys «
» and «
» find the needed page.
2.4 Making measurements
Before using the device for measurements, make sure that the battery has a sufficient level of
charge; the level of charge is indicated on the graphical display in the form of a battery (the indicator).
A completely dark indicator indicates that the battery is 100% charged. One line inside the indicator
field corresponds to approximately 20% of the charge volume.
If there is no or insufficient charge, recharge the battery using charger.
2.4.1 Preliminary calibration of the probe
To exclude the influence of the transit time of ultrasonic oscillations in the delay lines on the
result of measuring the thickness of the product, it is necessary to calibrate the connected transducer
before making measurements, for which purpose:
1.
In the "MEASUREMENT" mode, press the key «
» And select the "CALIBER" mode.
2.
Set using the keys «
» and «
»The propagation velocity of the US, corresponding
to the reference measure on the device (6070 m/s).
3.
Clean the contact surface of the inverter from grease, if any.
4.
Put the transducer into the air, according to the instruction, on the display of the device "PULL
IN AIR", then confirm the action by pressing the key «
». The instrument will take a
measure and display a new instruction.
5.
Apply a layer of contact lubricant on the built-in reference thickness sample block.
6.
Install the transducer’s contact surface on the reference measure and press firmly, according
to the instructions, on the displays of the device "INSTALL ON THE SAMPLE", then confirm
the action by pressing the key «
». The instrument will measure and after the display of
the results go into the normal measurement mode.
Caution!
Preliminary calibration of the transducer should be carried out only on the sample (measure) built-in
the thickness gauge.
The operation of preliminary calibration of the transducer is desirable to be carried out in the event
of changes in operating conditions (a significant change in the ambient temperature), when the
converter is first turned on, after a prolonged intensive operation of the converter.
