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 recall,
calibrate & store a single element transducer setup
on the 38DL PLUS.
The 38DL PLUS has the ability to use
both dual and single element transducers.
When using a single element transducer,
it is necessary to recall a default setup
or a custom setup for the transducer being used.
In this example we will be using
a M112 direct contact transducer.
To get started connect the transducer
to the right most transducer connector on 38DL PLUS
and press the XDCR RECALL key.
Then use the UP & Down arrow keys
to select DEFAULT SINGLE ELEMENT
and then press ENTER.
We now have the ability using the UP & DOWN arrow keys
to scroll through the list of available setups.
In this case here we are going to recall
the default setup for the M112 transducer.
Once it is highlighted, press the Measure key
to recall the default M112 setup.
At this point we are now ready to calibrate,
we will calibrating to a five step carbon steel test block
with a maximum thickness of 12.50 millimeters
and the minimum thickness of 2.50 millimeters.
Now let’s couple to our thick sample
and press the CAL VEL key
and as we get a steady thickness reading
press ENTER.
Now use the up, down, right & left arrow keys
to enter the known thickness of the block,
in this example it is 12.50 millimeters.
Then press the CAL ZERO key
and couple to the thin sample
and as we get a steady thickness reading
press ENTER
and then use the up, down, right & left arrow keys
to enter the known thickness of the block,
in this example it is 2.50 millimeters.
To complete the calibration press the red Measure key
in the upper left hand corner of the key pad.
We can now go back and check
the thicknesses of the calibration block,
2.5 millimeters,
5.00 millimeters,
7.50 millimeters,
10.00 millimeters,
and 12.50 millimeters.
Now that we have calibrated,
we can go ahead and store the setup for this single element transducer.
Press the XDCR RECALL key,
the Active setup will be highlighted.
Press the SAVE/SEND key
and the SAVE SETUP screen will be displayed.
We first need to enter in a name for our custom setup
in the SAVE AS field.
This can be done using the Virtual Keypad,
in this example let’s use STEEL – M112 for our name.
Change the D to an S
then use the right arrow key in the Virtual Keypad
to tab over to the E
and change that to a T and continue on.
To erase letters or numbers we do not need
we can use the DELETE option in the keypad.
Once we are have edited the setup name
scroll over and highlight DONE and press ENTER.
This now brings us to the SAVE TO menu
where we can select the first available
USER setup location to save our custom setup.
Once your USER setup has been selected
press the ENTER key and then highlight SAVE
and press the ENTER again
to confirm the saving of the transducer setup.
Now that we have stored our calibration
as a custom transducer setup,
it can be recalled at any time on the 38DL PLUS.
To recall a Custom Transducer setup
simply press the XDCR RECALL key,
then use the down arrow key to scroll down
to CUSTOM SINGLE ELEMENT and press the ENTER key.
Here in this list you will see
your custom transducers setups that can be easily recalled
by using the UP or DOWN arrow keys to highlight it
and then pressing the red MEASURE key
to recall the setup to start making measurements.
This completes our session on how to recall,
calibrate & store a single element transducer setup
on the 38DLPLUS.
