5.2.2 Editing the User-defined Sound-velocity Values
To calibrate your gauge for the material you are measuring, use ElcoMaster™ 2.0 software to change the
stored material velocities.
Connect the gauge to your PC and the software, then follow the on screen instructions to change the
calibration values.
6 TAKING READINGS
Disclaimer: Inherent in ultrasonic thickness measurement is the possibility that the instrument will use the
second rather than the first echo from the back surface of the material being measured. This may result in
a thickness reading that is TWICE what it should be.
Responsibility for proper use of the instrument and recognition of this phenomenon rests solely with the user
of the instrument.
Other errors may occur from measuring coated materials where the coating is insufficiently bonded to the
material surface. Irregular and inaccurate readings may result. Again, the user is responsible for proper use
and interpretation of the measurements acquired.
6.1 BEFORE YOU START
•
Prepare the surface - see "Condition and Preparation of Surfaces" on page 18.
•
Set the zero point of the transducer - see "Setting up the Gauge" on page 7.
•
Select units; press
to select metric (mm) or imperial (inches).
