Power Up
Press the switch on the back of the readout to power up the system. A
series of tests will check that the display, keypad, and memory are all
working properly.
If a problem is detected, an error code will appear on the screen. (Error
messages and solutions are listed on pgs. 31 - 32.) It is important to
note that the E1 message will appear every time you power up your
system and does not indicate a problem. It merely indicates that the
system had lost power. To acknowledge the message, press the CLEAR
key and proceed to the DRO mode.
Note: If the E1 message appears at any other time during normal
operation, refer to pg. 31 for possible problems and solutions.
Display Saver
When the system is not used for more than 90 minutes, a decimal point
will “scroll” across the X-axis display, indicating that the display saver
has been activated. The display saver, like a screen saver on a computer
monitor, will help prolong the life of your readout.
If the display saver has been activated, press any key on the readout or
move the table to return to the normal DRO view.

MICRO-LINE Reference Manual
SETUP
Parameter Setup
There are four parameters that you can define on your system:
• Display resolution (diS)
• Linear error compensation (LEC)
• Scale resolutions (rES)
• Scale count directions (Ct dir)
Establish each setting the first time you power up the system. You can
change the parameters later by returning to Setup and then using the
ENTER key to scroll to the appropriate category.
Anytime you change the linear error compensation, or count direction
for an axis, the absolute and incremental displays for that axis will be
reset to 0. If you change these settings, you will need to re-establish the
datum point.
For international units using 5µm (0.0002”) scales with reference
marks, you will need to recall Datum. Refer to pg. 38 for instructions.
When in the Setup mode, use the CLEAR key when you want to backspace, restore the previous value or access the previous parameter.

SETUP
How to Determine the Linear Error Compensation
Follow this procedure for each axis:
• In the DRO mode.
• Place a standard of known length on the table. Make sure it’s parallel
with the table’s travel.
• Put the readout in the absolute display mode (ABS/INCR key).
• Using an edge finder or dial indicator, locate one end of the standard.
• Press the ZERO key twice for the axis you are measuring. “0” should
appear on the display.
• Move the table along the axis until the edge finder or dial indicator
reaches the opposite end of the standard.
• Write down the length that is shown on the readout display for
that axis.
• Use the formula below to calculate the LEC for the axis you just
measured. Enter the result in the LEC screen (previous page).
Note: If the measured length is greater than the standard length the
LEC value will be negative.
Formula
S = Standard length
M = Measured length
Example
If the length of the
standard you used is
10” and the measured
length along the Xaxis is 9.995”, then
the LEC for the Xaxis is 500 parts per
million (PPM).

Testing the Scales
Follow these steps to confirm that the scale has been installed properly.
The Counting Test will confirm the scale’s electrical operation, and the
Repeatability Test will check the installation integrity.
Counting Test
• Move the table along each axis, one at a time. Check that the
readout correctly displays the table’s movement. If it doesn’t, then
the scale resolution you selected may not be accurate. Refer to
Scale Resolution on pg. 9 for instructions.
Repeatability Test
• Locate a magnetic base and dial indicator on the end of the scale.
Zero the readout and the indicator.
• Move the axis through the full travel and return the dial to “0.”
The readout should also read 0 (±.0005” for 10µm scales;
±0.0002” for 5µm scales). If it doesn’t, then the scale cable may
be loose, or the scale, mounting bracket, or reading head may
need to be tightened or realigned.
• Repeat these steps for each scale.

O P E R AT I O N
Setting the Datum (Absolute Zero)
MICRO-LINE allows you to measure both absolute and incremental
dimensions. A dimension measured from the point you define as the
datum is an absolute dimension. A dimension measured from any other
point on your print is an incremental dimension.
Datum, also known as absolute zero or workpiece zero, is the reference
point from which
When the readout is in the ABS mode, it is actually measuring the distance from the datum to the table’s current position.
You will need to establish a datum for every job. Your datum may
already be identified on your print; if it isn’t, then establish a datum that
allows you to enter most of your part’s dimensions directly, with the
least number of calculations.
All of the dimensions in the drawing below are based from the datum.
MICRO-LINE will base all of your part’s coordinates.
Datum
12
MICRO-LINE Reference Manual
OPERATION
If you are using 5µm (0.0002”) scales (international units only),
MICRO-LINE can recall your last datum position each time you
power up the system. Refer to pg. 38 for the proper procedure.
To set the datum at the tool’s current position:
• Position the workpiece on the table. Move the table until the tool is
centered on the edge of the workpiece at the location where you
would like to establish the datum.
• Using the ABS/INCR key, select the absolute (ABS) mode.
• Press the X-axis ZERO key twice to establish the current X-axis
position as the datum. Repeat for the Y- and Z-axes.
To set the datum using an offset:
• Using the ABS/INCR key, select the absolute (ABS) mode. Also
check that the proper measurement (inch or mm) is selected.
• Move the tool to a known point, i.e. the outside diameter of the
workpiece or the face of the workpiece.
• Press the ZERO key for the axis (X, Y or Z) you are entering a
dimension for.
• Using the keypad, enter the distance from your tool’s current
location to the point you want to establish as the datum. Include a
decimal point (.) and minus (-) sign when necessary.
• Press the ZERO key for another axis, or press ENTER to return to
the DRO display.

OPERATION
Incremental Dimensions
As described earlier, incremental dimensions are measured from the
current tool position to the next. If the tool is currently at 2” and you
want to move an additional 3.125”, you would select the incremental
mode, zero out the axis, and move the table until the display reads
3.125.
An example of how to measure using incremental dimensions is shown
on the next page.
To use an incremental dimension:
• Move the table to the point where you want to measure an
incremental distance from.
• Using the ABS/INCR key, select the incremental (INCR) mode on
the readout. Also check that the proper measurement (inch or mm)
is selected.
• Press the ZERO key below the axis(es) from which you are measuring.
• Move the table. MICRO-LINE will display the table’s position in
relation to the “0” point(s) for the axis(es) you chose.
After you have reached the position you want and have milled the part,
you can “zero” each axis again and then measure from that location to
the next point on the workpiece or press ABS/INCR to return to the
absolute mode.

OPERATION
Example: Incremental Dimensions
Let’s say that your print looks like this:
Hole 1 is an absolute dimension (measured from the datum), while
Holes 2 and 3 are measured incrementally. By putting
the incremental mode for the last two holes, you can measure their
distances just as the print specifies, without any calculations.

6. Now repeat the process for the third hole. Press the ZERO key for
the X-axis to measure from your tool’s current position.
7. Move the table until X = 2.00” and Y = 0.000”. Drill Hole 3.
Using Incremental Presets
In the standard incremental mode, you would reset the display at “0”
and move the table until the scale counts up to the point you want to
reach. With the preset feature, you enter the distance you want to move
first, and then count down to 0. For instance, if you enter 3.125” as the
preset distance, MICRO-LINE will show -3.125 on the display.As you
move the table in the positive count direction, the system will start
counting. When the axis display reads “0,” your tool is in the correct
position.
To preset an incremental position:
1. Press the key (X, Y, or Z) for the axis you want to preset.
MICRO-LINE will automatically switch to the incremental mode.
2. Enter the distance from your tool’s current position to the final
location. Include a decimal point and minus (-) sign when
necessary.
3. Repeat the step above for another axis or press ENTER to return
to the DRO display.
To reach the preset position, move the table until the display for each
preset axis reads “0.”

OPERATION
Running a Bolthole Pattern
When you run a bolthole pattern, MICRO-LINE always assumes that you
want to start with the first hole. It will display “Hole 1,” and then the
distance to the hole from your tool’s current position. Move the table
until it reaches 0, 0. After you’ve drilled the hole, press the
key again, and “Hole 2” will appear. Move the table to “0,” drill the
hole and continue with the rest of the pattern. If you want to start at a
different place in the pattern, press
BOLT USE followed by the number
of the hole you want to begin with.
Notice that the system automatically switches to the incremental mode
whenever you run a pattern. That’s because the system is using incre-
mental presets (pg. 17) to measure from one hole to another.As with
any preset, you can find the current hole’s location by moving the table
until the displays for both the X- and Y-axes read “0.”
After you’ve completed the operation, you may either keep the readout
in the incremental mode or press the
ABS/INCR key to switch to
absolute measurements.
BOLT USE
To run a bolthole pattern:
• Press the BOLT USE key. "HOLE" will
appear on the X-axis display. The number of
the first hole to be milled will appear on the
Y-axis display. (To select a different hole,
refer to the note on the next page.)
• MICRO-LINE will display the distance to the hole you’ve chosen.
Move the table until the X- and Y-axes both read “0.” Drill the first
hole.
• Press the
Y-axes read “0.” Drill the second hole. Repeat the procedure for
each hole in the pattern.

Conventions
This section identifies the standard conventions that apply to your
MICRO-LINE system.
DRO Mode
The MICRO-LINE system is considered to be in the DRO (digital readout) mode when the X- and Y-axes positions are displayed for a 2-axes
system, and the X-, Y-, and Z-axes positions are displayed on a 3-axes
system.
Count Direction
MICRO-LINE uses positive and negative numbers to determine the posi-
tion of the table and tool on each axis. The graphic below shows a typical setup for the positive and negative count directions for the X-, Y-,
and Z-axes on a vertical knee mill. All of the examples in this manual
are based upon this setup.
X-axis:
The table will move to the left and the
tool will move to the right for a positive count direction.
Y-axis:
The table will move toward you while
the tool moves away from you for a
positive count direction.
Z-axis:
The quill will move up (away from the
table surface) for a positive count
direction.

Recalling the Last Datum Setting For
International Units
If you are using 5µm MICRO-LINE scales, MICRO-LINE can retrieve
your last datum setting when you power up your system. This feature is
especially useful when you have to shut down the system in the middle
of a job, or if a power interruption occurs. When power is restored,
MICRO-LINE will use Position-Trac
reference marks and recall the datum within seconds.
The recall feature only works after you have completed the initial
system setup and established a datum, so it won’t be accessible the
very first time you turn the readout on. After you have completed those
operations, you can recall the datum for every power up thereafter.
To recall your last datum:
• Power up the system.
TM
technology to read the scales’
• Press the CLEAR key to clear the E1 message.
• Press the decimal point (.) on the readout’s keypad. Move the
table in the positive count direction along the X-axis. Keep
moving it until the system recalls the datum and “found”
flashes on the screen. The system will automatically reset the
X-axis value to reflect the distance from the table’s current
position to the datum.
Repeat this step for the Y- and Z-axes, always moving the
machine in the positive count direction.
After you have completed the recall procedure, you can move to the
datum by positioning the table, saddle, and quill until the display reads
“0” for each axis.
