Hi, I'm Drew Klaber with Mitutoyo America Corporation.
I'm here at Jeremy Banks and today's Tool Tip, we're going to discuss
how to get started with your brand new Linnear Height Gage.
So, Jeremy, we have a brand new Linnear Height here, fresh out of the box.
Can you walk me through some steps that you would recommend
for getting up and go on with the new unit?
Right, so the first couple of things you're going to do
is you're going to have to zero out the linear scale.
You're going to have to calibrate the probe,
and then you're gonna have to set an absolute origin.
Great, can you show me how to do those right now?
Yeah, let's get started. Very good.
So Drew, as you can see, the gage is now ready for me to zero out the linear scale.
To do that, all I got to do is follow
the direction on the screen and move the slider to the highest position.
So I'm going to do that now.
So all I'm going to do is move the slider up
to the top of the unit and it should beep when I hit the home position.
Oh, that's easy enough.
And now you can see your displays changed.
Yeah, so now I've zeroed out the scale.
Now it wants me to set the probe and the absolute origin.
So let's go ahead and do that.
I'm going to go ahead and hit the probe calibration button,
and then I'm going to select method two, which is using the included artifact.
Now the machine will automatically go up and measure at the bottom of the artifact.
As you can see on the screen, it now wants me to position the probe
so that I can measure the top of the artifact.
So I'm going to go ahead and move it.
Once the probe is in position, I'm going to press the Enter key to continue.
As you can see now, the probe diameter measures 4.9940,
so the probe diameter has been calibrated.
So now, Drew, the last thing we have to do is set the absolute origin to do that.
I'm going to hit the Datum button
and I'm going to select the first option to just measure down.
Now the probes made contact with the granite.
And you can see back on the display that the granite now measures zero.
Well, that's pretty easy to get up and going.
And it didn't take very much time at all.
No, no. It's actually very easy to get going. It's quick.
The gage is now ready to use.
If I have a small to medium sized part, I can measure with no problem.
What if you have a larger part
that maybe extends a little bit beyond the normal measuring range?
Well, as you can see, the probe holder has two positions,
so I can actually change. Right. Right.
There's one on the bottom and one on the top.
So I can actually switch from the lower position to the upper position.
And then all I have to do is re-zero.
So we'll take a couple of minutes. I'll show you how to do that..
Perfect.
Drew, as you can see, there's two positions on the slider.
The probe is currently in the lower position,
and I want to move it up to the top.
So I'm going to hold the slider so that it doesn't pull it back up
with a counterweight when I remove the probe.
Now, there's a little notch or an indentation on the probe
that I'm going to line up
when I inserted into the top slot to make sure that it is oriented correctly.
I'm going to go ahead and... So this would beep for putting it in incorrectly?
Yeah, it's meant to be used either in an up position or down position.
At a different angle, you're not going to get the rigidity
that you need to get accurate measurements.
So the first thing I'm going to do
is hit the Datum button on the front of the screen.
And then I'm going to select option number four, which is a preset.
So to continue, I'm going to hit Enter.
So the measurements been made
and now the display wants to know what the offset value is.
So it's a 390 position on the Check Master.
Now, what you want to do to be sure, is you want to take your certification
for the Check Master and make sure that you put in the exact value.
And it's probably not going to be 390,
it's probably going to be 390 and then a bunch of decimal places.
So make sure that that accurate value is put into this box.
Once you're satisfied, go ahead and hit Enter to except the changes.
And that's very easy to do, but what if I don't have a check master like this?
Well, you could use a stack of gage blocks
or you could use a master part that has a certified value.
So, again, even if I'm using a gage box
in a master part, always go back to the certified value?
Yeah, always use that certified value.
The whole point of this is you're zeroing the the probe position.
If the probe position
isn't accurate than none of your height measurements will be either.
Understand. Jeremy, thank you for your time. Thank you for your time as well.
