- Hi, my name is Steve Matthews with AgWeb.
Today we're gonna do a walkthrough
on the Fixturlaser Level.
Which is essentially a high precision
digital machinist level.
This is the device.
Out of the box, it is calibrated
to earth level so no field calibrations required.
This is the charging port and it communicates by Bluetooth
with the NXA or NXA Ultimate.
And of course it's also got a battery indicator
like other Fixturlaser sensors.
So the Fixturlaser Level is a dual axis,
high precision level.
As you can see, on the device itself,
we have a beta direction and an alpha direction.
So when we come over here to the NXA,
the level icon looks like two little sticks and a sensor
and we turn it on and we instantly have
a high precision level measurement on this base.
So the application for Fixturlaser Level
is gonna be a lot of mainly base leveling,
and so we have a mock up of a small base here,
12 by seven inches,
and what you'll see on the read out of the NXA
is thousandths per inch.
The display says 6.0 per one thousand.
So what this means is the increments,
6.0, is in thousandths.
six thousandths point 0
so those would be 10 thousandths.
If we come in here into the settings menu
we can select the level of precision
we want to read out to.
For today's measurement
one 10 thousandths of an inch is plenty,
but there is also a selection
to go out one more decimal place.
That gives us an overall possibility
of measuring down to about one ten thousandth per foot.
So what we're gonna do is walk through
the different features of how the level works.
As I set it down on my base mockup,
I see I have a measurement of six thousandths per inch.
So it says six per 1,000 so that's thousandths
per 1,000 thousandths.
So that is thousandths per inch.
What we have is a base that's about 12 inches long,
and so according to this reading,
and I'll work in just one direction
to make this demonstration a little bit simpler,
but it does measure in both directions.
So at six thousandths per inch, over 12 inches,
I am out of level by approximately 72 thousandths.
I have a couple of 75 thousandths shims here,
and I will lift up this base,
and you can see on the display unit,
it's changed from six to one.
So I've leveled this out to within one thousandth
per inch, if you want to translate that to
thousandths per foot, which is common amongst
machinist levels, spirit levels
like a Starrett 98, or Starrett 199.
That would translate to 12 times
to get a per foot measurement.
So one thousandth per inch
is 12 thousandths per foot.
So as you can see when we take the shims back out,
we go back to six thousandths per inch.
So we'll put the shims back in to level it up
And the next thing we'll do is go through
how to qualify the unit to a fixture.
The Fixturlaser Level sensor
is calibrated out of the box.
However, there may be cases where we want to use
some type of fixturing in conjunction with the sensor.
So to demonstrate how we do that,
I will assemble the sensor with a mag base.
Other options might include a longer straight edge
to take a level measurement over a broader area
than just the three inch by three inch surface
of the level sensor.
We've already leveled this base to within
about a thousandths per inch.
However, at this time, after I've put the sensor
on a fixture, I now have different readings.
That's because the sensor is not qualified
to the fixture that it's on.
This is a very short and easy process.
What we do is zero the sensor,
turn the fixture 180 degrees,
and half the value.
Now I have a true earth level reading of the base.
And again, I'm back to within a thousandths per inch,
since I leveled this base already.
And that is the qualification process
for qualifying the Fixturlaser Level sensor
to a fixture.
Now that we've set up the Fixturlaser Level,
taken measurements, leveled a base,
put a fixture on, qualified the fixture,
now we will go through how to record the values,
and this is one of the biggest values of the
Fixturlaser level is that
unlike a spirit machinist level,
we can now record the values
that we've measured.
So, I hit the record button,
check for yes, and now I have two choices
on how to record the data.
I can record one at a time,
so for example, I might record this corner
this corner,
and finally the fourth corner.
This records one measurement at a time,
and the other button records a series of
measurements in a time capture.
And that turns the time capture off.
And then I turn off the recording.
So I'm back to a live measurement,
the other option that I have for
saving and measuring data
is to take a full measurement.
Now the reason why you might want to do this
is to filter out some ambient vibration.
So this takes a measurement over, in this case,
a five second period.
That period is user definable,
and once you've hit that button,
you can then record this measurement.
So if there is some variation in it moving around,
for example, because the area is shaking some,
then I can smooth out that vibration
by taking an average to capture.
