Hello, my name is Nina Giombetti
and I’m a sales engineer for Olympus Ultrasonic Thickness Gages.
Today, we are going to discuss how to calibrate
the 38DL PLUS with a standard D79X series dual element transducer.
These transducers have a center pin for probe recognition.
Simply plugging them into the 38DL PLUS
allows the gage to automatically recognize the transducer
and recalls the default parameters for that probe.
To start simply plug in any D79X series transducer.
The gage will prompt the user to perform a Do-Zero.
This is done by wiping the couplant off the tip of the probe
then pressing the 2nd FUNCTION and CAL ZERO button.
The gage will automatically go out
and measure the time of flight
to the transmit and receive side of the transducer,
allowing the gage to compensate for any changes
in the transducer due to wear or temperature.
At this point we are ready to perform a two point calibration.
In this example, we are going to be calibrating
to a five step carbon steel test block
where the maximum thickness is five hundred thousandths (inch)
and the minimum thickness is one hundred thousandths (inch)
with one hundred thousandths (inch) steps in between.
Simply couple to your thick standard,
in this case the five hundred thousandth step
and press the CAL VEL key.
Once we have a steady reading press the ENTER key.
You can now use the right, left, up or down arrow keys
to enter in the known thickness value of the standard.
Now you can proceed to the thin standard,
the one hundred thousandth step.
Couple on to the thin standard
and press the CAL ZERO key.
Once we have a steady reading press the ENTER key.
Now again you can use the up, down,
left and right keys to enter in
the known value of the thickness standard.
Then press the red MEASURE key
to complete the calibration.
We can now go back to the calibration block
and check your standards.
One hundred thousandths
Two hundred thousandths
Three hundred thousandths
Four hundred thousandths
and Five hundred thousandths.
This completes the two step calibration
for the 38DL PLUS
with the Olympus D79X Dual Element Series transducers.
