Overview
This manual will guide you through the installation, setup, and operation
of the MICRO-LINE system. Use it to get your system up and running
“out of the box” and as a quick reference guide for your day-to-day
operations.
We recommend installing the scales first, according to the instructions
included with your system. After the scales are in place, install the
readout and then finish setting up the system.
Here’s how a typical machine will look after the installation is complete:

INSTALLATION
Installing the Scales
Install the linear encoders according to installation instructions found
within your Micro-Line system manual. These general installation
instructions are found on page 33. Read these instructions completely
even though bracket kit instructions supersede them.
Installing the Readout
Follow the readout installation instructions that are included with your
mounting arm bracket kit. The electrical specifications for the readout
are listed on pg. 27.
After the installation is complete, proceed to “Power Up.”
MICRO-LINE Reference Manual

INSTALLATION
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. 25 - 26.) 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. 25 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 any axis to return to the normal DRO view.

MICRO-LINE Reference Manual
SETUP
Parameter Setup
There are 3 to 4 parameters that you can define on your system:
• Display resolution (diS)
• Linear error compensation (LEC)
• Scale count directions (Ct dir)
• Input 3 ON/OFF for international units
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’ll need to reestablish the
datum point.
For international units using 5µm (0.0002”) scales with reference
marks, you will need to recall Datum. See page 32.
When in the SetUp mode, use the CLEAR key when you want to backspace, restore the previous value or access the previous parameter.

Linear Error Compensation
With MICRO-LINE, you can compensate for machine tool wear. If you
know the linear error compensation (LEC) value in parts-per-million
(PPM), you can enter it directly.
If you don’t know the LEC, use the formula on the next page to determine
the value for each axis.
To change the linear error compensation:
• Move to the “Linear Error Compensation” display in the Setup
mode. (Press SETUP and then the ENTER key until “LEC”
appears).
• Press the
MICRO-LINE will display the current LEC value for that axis.
• Using the keypad, enter the linear error compensation factor
(in PPM), followed by the ± key for negative values. The number
must be within -9999 and 9999 (use whole numbers). The formula for
calculating the value is on the next page.
• After you complete setting your LEC, press ENTER to
continue with setup or press ENTER then SETUP to return to the
normal DRO display.

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 machine. Make sure it’s
parallel with the axis being measured.
• Put the readout in the absolute display mode (ABS/INCR key).
• Using an 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 indicator along the axis until it 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 parameter (previous page).
Note: If the measured length is greater than the standard length the
LEC value will be negative.
Formula
M = Measured length
LEC =
(
S - M
M
)
x 1,000,000S = Standard length
Example
If the length of the
standard you used is
10” and the measured
length is 9.995”, then
the LEC for that axis
is 500 parts-per-million (PPM).

SETUP
Count Direction
Use the count direction setting to define the positive counting direction
for each scale. The direction will be displayed as a “1” or a “2” (the
numbers are not assigned to a particular direction). You only need to
change the count direction if the scale is counting in the negative
direction during a positive move, or vice versa.
Refer to Conventions (pg. 31) for more guidelines.
To change the count direction:
• Move to the “Count Direction” display in the Setup mode. (Press
SETUP and then the ENTER key until “Ct dir” appears).
• Press the appropriate axis key (

SETUP
Testing the Scales
Follow these steps to confirm that your scales have been installed properly. This test will confirm the scale’s electrical operation, and will also
check the installation integrity.
• Locate a magnetic base on the machine and set the dial indicator
on the scale’s reading head casting. 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.

Radius and Diameter
Pressing the RAD/DIA key lets you view the X-axis dimension either as
a radius or as a diameter.
Display resolution is affected by the RAD/DIA key.

MICRO-LINE Reference Manual
OPERATION
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 machine axis’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 measure 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.
MICRO-LINE Reference Manual
13
OPERATION
If you’re 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. 32 for the proper procedure).
To set the datum at the tool’s current position:
• Position the workpiece in the chuck. Move the tool until
it is positioned 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 Z-axis.
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.
• Using RAD/DIA key, select the Radius mode.
• 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 once for the axis (X or Z) for which you’re
entering a dimension.
• 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 the other axis, or press ENTER to return
to the DRO display.

OPERATION
Incremental Dimensions
As we described earlier, incremental dimensions are measured from the
current tool position. If your 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 axis until the display reads 3.125.
An example of how to measure using incremental dimensions is shown
on page 17.
To use an incremental dimension:
• Move the machine axis to the point from where you want to
measure an incremental distance.
• Use the ABS/INCR key to 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’re measuring.
• Move the machine axis. MICRO-LINE will display the machine
axis’position in relation to the incremental “0” point(s) for the
axis(es) you chose.
After you’ve reached the position you want and have machined the part,
you can “zero” each axis again and then measure from that location to
the next point on your workpiece or press ABS/INCR to return to the
absolute mode.
16
MICRO-LINE Reference Manual
Example: Incremental Dimensions
Let’s say that your print looks like this:
Using Incremental Zero
In order to cut a groove to a depth
of 0.120” from the 1” radius, it is
necessary to establish a zero at 1”.
This can be done using the incremental mode without changing the
Datum. Follow these steps:
1. Move the tool until the readout display
shows that the X-axis = 1.0000” and
the Z-axis = 2.0000” in the absolute mode.
2. Press the ABS/INCR key to switch to the
incremental mode.
3. Press the X-axis ZERO and the Z-axis
ZERO keys.
4. Begin cutting until the X-axis reads -0.1200”.
OPERATION
Using Incremental Presets
In addition to setting incremental zero at the current
tool position, you can also preset the incremental
zero from the current tool position. Enter the distance and direction you wish to move in relation to
your current position. Follow these steps:
1. Move the tool until the readout display shows that the
X-axis = 1.000” and the Z-axis = 2.0000” in the absolute mode.
2. Press the ABS/INCR to switch to the incremental mode.
3. Press the X key and press the following key sequence:
- . 1 2 ENTER then press the Z-axis ZERO key.
4. The X-axis display will show 0.1200”.
5. Begin cutting until the X-axis reads 0.0000”.

OPERATION
Tool Offset
The MICRO-LINE can store the dimensional offset of an additional tool.
This allows you to use two tools without having to reestablish zero as
you change between them. In order for this feature to work, the tools
must be able to repeat their location when they are changed (Repeatable
tooling). To use this feature you must first select the tool number (either
0 or 1).
1. Place your first tool in the tool holder.
2. Press the TOOL USEkey.
3. Press 0 to select the first tool, then press ENTER.
4. Set the Datum (Absolute Zero) using this tool. See page 13.

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-axis and Z-axis positions are displayed.
Count Direction
MICRO-LINE uses positive and negative numbers to display the position
of the tool along each axis. The graphic below shows a typical setup for
the positive and negative count directions for the X-and Z-axes on a
lathe. All of the examples in this manual are based upon this setup.
X-axis:
The axis will move away from the
center for a positive count direction.
Z-axis:
The axis will move away from the
spindle for a positive count direction.

Recalling the Last Datum Setting For
International Units
If you’re 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 on the readout. After you’ve 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
tool 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 tool’s current
position to the datum.
Repeat this procedure for the Z-axis, always moving the
tool in the positive count direction.
After you’ve completed the recall procedure, you can move to the datum by
positioning the tool until the display reads “0” for each axis.
Note: If Input 3 is being used, the datum will not be correct until both the
Z-axisand Input 3 scales have been recalled.

Installation Procedure
These steps apply to all mounting conditions. Although this may
not pictorially represent your application, your installation procedure should follow these steps.
ACU-RITE bracket kit instructions supercede this
section.
• Adjust drill depths and fastener lengths as required.
• Contact your authorized ACU-RITE distributor if assistance is
required.
First Steps:
1. Move the machine axis to its center of travel.
2. Mark the machine axis location so that it can be recentered
easily.
3. Slide the reading head with the alignment brackets attached,
along the scale case to the center of the scale case.
4. Locate the bottom of the end cap flush with the axis parting line.
5. Mark one end mounting hole.
6. Drill and tap the first end mounting hole. Drill and tap a
10-32 x 1/2” deep hole for a top mounting form or a
1/4-20 x 1/2” deep hole for an end mounting form. Attach the
scale.

7. Align to within .010” TIR to axis of travel and mark the second end mounting hole. Drill and tap.
8. Attach the scale and align to within .010”TIR to axis
of travel.
9. For the top mounting, form indicate to within .010” TIR over
each mounting hole and mark hole location. Drill and tap all
remaining holes. Attach the scale and align to within
.010” TIR to axis of travel.
10. For end mounting form, after scale is attached and
aligned, insert mounting hole covers.
11. Ensure the axis is still at its center of travel and the reading
head is centered on the scale. Mark the reading head
mounting holes.
12. Move the axis and drill and tap for 8-32 (M4).

13. Move the axis to align reading head mounting holes.
14. A gap may exist between the reading head and its
mounting surface, requiring leveling screw adjustment.
15. To adjust the leveling screws, place a .001" -.003" feeler
gage (or shim) between one leveling screw and the
mounting surface at a time.
16. Adjust the leveling screw until a slight drag is felt on
the feeler gage. Repeat this for each leveling screw,
3 total.
17. Evenly tighten the two 8-32 SHCS to secure the reading
head.
18. Use Allen wrench to slide brackets away from the reading
head.
19. Remove alignment brackets and save for future use.
20. Route cable with slack loops allowing for axis motion.
21. Secure excess cable by fastening with clips and ties.
22. Move the axis through its full travel. Confirm that the
assembly does not interfere with the machine movement.
