9-8 Using the Ultrasonic Thickness Gage
Calibrating the Thickness Gage
The ultrasonic thickness gage is factory calibrated; therefore, you
only need to perform calibration if you receive new transducers
or have a reason to doubt the accuracy of the readings.
To calibrate you will need:
• a test block, which is shipped with the thickness transducer (or
test block of known sound speed and length)
• ultrasonic couplant
To calibrate the thickness gage, you must enter the Calibration
Menu and then enter the appropriate data.
Entering the Calibration Menu
1. Press the [CAL] key to enter the Calibration Menu.
2. Press [F3] to select “WALL.”
3. Press the [CAL] key.
Enter Calibration Data
1. Use the numeric keys to enter either one of the test block
lengths, then press [ENT]. If you are using a GE Panametrics
supplied test block, the length is printed on the block.
2. Use the numeric keys to enter the other test block length, then
press [ENT]. If you are using a GE Panametrics supplied test
block, the length is printed on the block.
Note: To perform a one point calibration, enter the same
number for both lengths.
