Important Notice
The following information must be read and understood by any user of a GE Sensing & Inspection Technologies ultrasonic thickness gauge.
Failure to follow these instructions can lead to errors in thickness measurements or other test results. Decisions based on erroneous results
can, in turn, lead to property damage, personal injury or death.
General Warnings
Proper use of ultrasonic test equipment requires three essential elements:
•
Selection of the correct test equipment
•
Knowledge of the specific "test application requirements"
•
Training on the part of the instrument operator
This operating manual provides instruction in the basic setup and operation of the thickness gauge. There are, however, additional factors
which affect the use of ultrasonic test equipment. Specific information regarding these additional factors is beyond the scope of this manual.
The operator should refer to textbooks on the subject of ultrasonic testing for more detailed information.
