GENERAL INFORMATION
Introduction
Mitutoyo ProScale Series 950 Linear Measuring Systems are manufactured exclusively
for Mitutoyo America by Accurate Technology Inc., Asheville, NC
ProScale digital measuring systems are affordable precision electronic devices for
making linear measurements with speed and accuracy. They are ideal for most
measuring requirements up to 6m (20ft.) where high accuracy, 10 μm, (approximately
.0005”) is not needed, but affordable repeatability, (better than a tape measure), or
accuracy to 50 μm (.002”) is desired. Because ProScale shows the exact measurement
on its display, it eliminates the guesswork involved in reading and interpreting tape
measures, scales & pointer, or shaft encoders. It is compatible for retrofitting, or as
original equipment, on most machinery or for any general purpose measurement
application where data is collected (SPC, RS232, RS485) and/or digital accuracy and
repeatability is desired.
ProScale consists of a scale, a readhead (or encoder) and a digital display. It uses
capacitive encoder technology, the same technology used in Mitutoyo digital calipers.
Because ProScale is a solid-state electronic device there's very little to wear out. The
readhead and scale are designed to withstand shop dirt, dust, and other airborne
contaminants, and the controls are sealed with a protective cover. With normal care,
ProScale will last for years.
For ProScale systems with different measuring lengths, or different DRO’s with additional
capabilities and accessories please contact your Mitutoyo distributor or Accurate
Technology – www.proscale.com .
What This Manual Includes
This manual includes information for:
 Mitutoyo ProScale Series 950-404, 950-405, 950-406 & 950-407 linear
digital measurement systems, supplied with General Purpose LCD
Digital Displays with Firmware V2.0 and higher.

ProScale Terminology
All ProScale systems consist of a SCALE, a READHEAD, and a DIGITAL DISPLAY.
The SCALE consists of a series of conductive patterns bonded to an aluminum extrusion.
ABS Style Scale Pattern
The READHEAD, or encoder, contains a custom computer chip, which transmits and
receives signals to and from the scale using capacitive coupling. The received signal is
used by the readhead to calculate its position to within 10 microns (10m / .0004in). This
position data is then sent to the digital DISPLAY, where it can be displayed in millimeters,
centimeters, inches, or fractions and sent to an external data acquisition device via a 10
pin SPC connector.

Scales
An absolute, (ABS), system measures its actual position by reading a pattern which is
unique at any given location over its length. The maximum length of a ProScale absolute
pattern is 430mm (16.932 in.). The pattern must then repeat itself.
Consider the illustration above to represent a ProScale Model 950-406. There are three
absolute patterns (each pattern is 430mm long), joined together end to end. Within each
pattern the system is totally absolute. However, crossing over a pattern joint now
presents the readhead with information identical to what it read in the previous pattern.
At this point the system must be able to recognize that it has crossed over a pattern joint
and therefore must add or subtract the value of 1 pattern offset - 430mm. In fact, each
time the readhead passes over a pattern joint it must keep track of how many patterns it
has passed, and in which direction. This action is accomplished by the digital display.
What does all this mean? If the readhead remains on the same absolute segment, it can
have power removed, its position changed and power restored without loss of position
information. However, if power is removed and the readhead passes over a pattern joint,
the transition will not be recognized. When power is restored the system knows its
absolute position on the new pattern, but does not know how many patterns it has
passed, or in which direction!
ProScale displays provide the operator with a method to adjust the pattern offset so the
system displays the correct reading at all times without loss of accuracy. See Section 4
All ABS scales have a “zigzag” pattern etched onto the green laminate. Take care to not
damage this etching or remove the green coating. There should also be a pattern
“break” approximately every 430mm (17in.). Do not attempt to shorten ABS style
scales; call Accurate Technology 800-233-0580 for assistance or visit
www.proscale.com .
Readheads
ABS readheads have “BLACK END OF SCALE” labels on the cover, and the wire exits
from the corner of the housing. Extreme care must be taken not to damage the six brass
“fingers” inside the readhead housing. ABS style readheads, used in all 950 Series
systems, must be mounted on ABS scales with a particular orientation. Each readhead
has an arrow on the label pointing in the direction of the “BLACK END OF SCALE”
(each ABS style scale will have one end painted black). This relationship is very
important, since the readhead will work, but produce erratic results if incorrectly installed.
To insure proper operation, be sure the arrow on the readhead is pointing toward the
BLACK end of the scale. The standard readhead has 2m (6 ft.) of cable. For special
cable lengths, contact Mitutoyo America or Accurate Technology.

AND
950-405
ProScale 950-404 and 950-405
General Purpose measuring system with standard measuring ranges of 250mm and
450mm.
950-404/405 systems use ABS style scales, ABS style readheads, and general-purpose
digital displays. Neither the scale nor readhead are compatible with older Mitutoyo
Incremental (950-401, 950-402, 950-403, 950-410, 950-411, 950-414, 950-415, 950-416,
950-417, 950-419, 950-421, 950-422, 950-423) ProScale systems.
.
ProScale Model 404/405 is easy to install. By following the basics of good installation,
reliable, error-free operation can be expected. ProScale can be used in many different
measurement applications, and with numerous types and brands of equipment. Therefore
all installations will be a little different and it is the responsibility of the installer to choose
the bolts, screws, or other mounting hardware that guarantee proper installation for
optimum operation.
Installation
1. Note the orientation of the readhead on the scale. Be sure the arrow on the readhead
points towards the “BLACK END OF SCALE”. This orientation is critical for proper
operation of ProScale. Be sure the mounting location for the readhead and scale will
allow this orientation. Take care when sliding the readhead onto the scale so the brass
“fingers” inside the readhead do not get damaged. (A slight “wiggling” motion when
installing the readhead on the scale will simplify the process.)
Mitutoyo America Corp. - ProScale Series 950

2. Determine an appropriate mounting location for the system. Most applications of the
Series 404/405 will have the readhead held stationary while the scale is passed
through the readhead. The ProScale will also operate properly if the readhead is
moved along the scale (see figures on next page).
3. If the readhead is to be mounted stationary, the scale should
be attached to a moving part of the measuring application or
machine using the included Connector Link.
Mount the readhead using three screws or bolts. Mount one
end of the connector link to the scale using an M5 (or 10-32)
screw and the other end to the moving part. Check that the
scale is properly aligned with the direction of motion of the
Connector Link
moving part. Be sure both connections are secure or
PN 100-1025-005
inaccurate/erratic readings could result. (The connector link
compensates for small misalignments of the installation and
acts as a shear pin). The connector link must be mounted in the same direction as the
scale (see figure below).
Note: Failure to use the connector link could void the warranty.
4. If you choose to hold the scale stationary and move the readhead to measure, you
should use the included Guide Clip to move the readhead along the scale (see figure
on next page). The connector link is not necessary in this
configuration.
Mount the scale using a M5 (or 10-32) screw. Be sure the scale
is properly aligned as the readhead is moved (the Guide Clip
will compensate for slight misalignment in one direction only).
Adjust scale alignment if necessary.
For accurate measurements, the guide clip must be mounted
perpendicular to the direction of travel of the readhead. The
Guide Clip
guide clip should exert some pressure over the full range of
PN 100-1026-005
travel on the readhead so the two move as a single unit.
Note: Failure to use the guide clip could void the warranty.
5. The Digital Display may be mounted in a location which allows for easy viewing by the
operator. The location of all parts should also safeguard the cable from possible
damage. ProScale wiring should be kept away from electrical wiring and motors. Plug
the readhead into the display. See Section 4: Digital Display Operation.

Calibration
Once installed, ProScale can be calibrated easily and quickly. Following is an example
for calibrating ProScale on an industrial wide belt sander. Other installations follow the
same general procedure.
1. Check to be sure installation of all parts is complete, all fasteners are secure, and the
readhead is plugged into the digital display.
2. Set-up the machine to operate as normal. Run a part through the sander.
3. Measure the thickness of the sanded part with the most precise measuring tool
available (digital calipers if possible).
4. Press the zero key on the ProScale digital display then press and hold the PLUS key
to scroll until the thickness measurement is displayed (The longer the PLUS key is
held down, the faster the display will scroll).
5. When the proper reading is reached, lock the display if desired. This prevents
accidentally re-zeroing of the display. See Section 4: Lock Mode.
If the direction of movement (+ and -) on the digital display is opposite the desired
direction, the display programming should be changed.
See Section 4: Programming (Programming Parameter Pr0).
Maintenance
Although the ProScale will operate in a dry environment of non-conductive debris such as
sawdust, the system should be cleaned of excess debris when necessary. This will
prevent premature damage to the scale or readhead. Should the scale become difficult
to move, check to see if debris has built up under the readhead and remove if necessary.
Find and remove any burrs which may have developed on the aluminum scale. Do not
use any liquid lubricants on the scale assembly, as this may impede the readhead's
ability to operate properly and will attract other contaminants to the scale.
The Digital Display should be cleaned periodically with compressed air to remove any
dust on the lens and keys.
All mounting fasteners should be checked occasionally for tightness.

ProScale 950-406 and 950-407
General Purpose measuring system with standard measuring ranges of 1.2m and 2.4m.
950-406/407 systems use ABS style scales, ABS style readheads, and general-purpose
digital displays. Neither the scale nor readhead are compatible with older Mitutoyo
Incremental (950-401, 950-402, 950-403, 950-410, 950-411, 950-414, 950-415, 950-416,
950-417, 950-419, 950-421, 950-422, 950-423) ProScale systems.

2. Determine an appropriate mounting location for the system. Most applications of the
Series 406/407 will have the scale held stationary while the readhead is moved along
the scale. However, the ProScale will read correctly if the readhead is moved along
the scale or if the scale is moved through the readhead.
3. When the scale is stationary and the readhead moves to measure, you should use the
Guide Clip to move the readhead along the scale (see figures below). Mount the scale
using M4 (or #8) screws. Be sure the screw heads do not protrude
above the surface of the extrusion. Check that the scale is properly
aligned as the readhead is moved over its length (the Guide Clip will
compensate for slight misalignment). Adjust scale alignment if
necessary. For accurate measurements, the guide clip must be
mounted perpendicular to the direction of travel of the readhead.
The guide clip should exert some pressure over the full range of
travel on the readhead so the two move as a single unit.

Calibration
Once installed, ProScale can be calibrated easily and quickly. Following is an example
for calibrating ProScale on a table saw fence. Other installations follow the same general
procedure.
1. Check to be sure installation of all parts is complete, all fasteners are secure, and the
readhead is plugged into the digital display.
2. Cut a part using the normal fence operation.
3. Do Not move fence until calibration is completed.
4. Measure the dimension of the part with the most precise measuring tool available (i.e.
digital calipers).
5. Press the zero key on the ProScale digital display then press and hold the PLUS key
to scroll until the measurement you just made is displayed. (The longer the PLUS key
is held down, the faster the display will scroll).
6. When the proper reading is reached, lock the display if desired. This prevents
accidentally re-zeroing of the display. See Section 4: Lock Mode
If the direction of movement (+ and -) on the digital display is opposite the desired

SECTION 4
DIGITAL DISPLAY
This section covers the programming and operation of the Series 950 LCD DRO
(Firmware V2.0 and higher). This display is supplied on all Mitutoyo ProScale 950 Series
Digital Measuring Systems.
The LCD
The above figure illustrates all the segments available on the Digital Display.
Display Keys
Key Press Timing
The keys pictured above, found on all Series 950 LCD Digital Displays, have multiple
functions. Timing, that is how long a key is depressed, and the combination of the keys
pressed is important. This manual uses the term ‘”momentarily” to describe a key press
of typically less than 1 second. Whereas “press and hold” is used imply a key press of
typically longer than 1.5 seconds. As an example; when using a PC keyboard to type a
capital letter you would “press and hold” the SHIFT key and “momentarily depress the
LETTER key.
In addition the key(s) “function” is executed on the key RELEASE, not the key
DEPRESS. This is important since some keys execute different functions based on how
long they are depressed. These key operations, once tried, quickly become intuitive.
Mitutoyo America Corp. - ProScale Series 950
17 of 36
ON/OFF
Momentarily pressing the ON/OFF key will cause the display to turn on or off. The
Firmware Version is displayed on power-up or when ON/OFF key is pressed. While on, if
no key presses or positional changes occur within 15 minutes, the Digital Display will
automatically turn itself off to conserve battery life. While off, if a position change is
detected (.05mm or .002in) or the ON/OFF button is pressed, the display will
automatically turn itself on with no loss of measurement information.
(Programming Parameter Pr8. Factory default set to 15 minutes.)
Battery voltage is displayed by pressing and holding the ON/OFF key for 5 seconds while
display is turned on.
CAUTION: Pressing and holding the ON/OFF and MODE key for 10
seconds while the display is turned off will perform a full segment LCD
test AND re-set all programming parameters to factory defaults.
MODE
The digital display can show measurement information in Imperial or Metric. To change
the current display mode, momentarily press the MODE key. With each key press the
display will cycle through decimal inches, fractional inches (1/16), (1/32), (1/64) (If
enabled by Programming Parameter Pr6) and metric (mm or cm based on setting of
Programming Parameter Pr5).
When the display is in a decimal mode (mm, cm or in) it will auto-range to the next
resolution if the value is displayable in the next range. This allows the display to be used
with other Mitutoyo products in inch mode or different resolutions other than 2 decimal
places.
When the display is in 1/16 or 1/32 inch fraction mode, a series of “bars” in the upper
right corner of the LCD each represent an additional 1/64th of an inch measurement. ie.
When in 1/16 inch mode and three bars are showing, the measurement displayed is
rounded down to closest 1/16 inch and each illuminated bar indicates an additional 1/64
of an inch (“heavy”) measurement. For better resolution switch to 1/32 or 1/64 fraction
mode. For the best resolution switch to a decimal mode.
When the measurement is greater than + 99 63/64 inches, a +100 or +200 will show in
the upper right portion of the LCD to indicate this amount must be added to the displayed
reading. ie: if the measurement is 154 5/8 inches, 54 5/8 and +100 will be displayed on
the LCD. If the measurement is -307 23/64 inches - 7 23/64 , +100 and +200 will be
displayed on the LCD.
The Resolution of the display can be set for Normal; (.01mm or .001in), Reduced; (.1mm
or .01in) or Increased; (.01mm or .0005in) (Programming Parameter Pr4.)

+, 0, and – Keys
The + (plus), 0 (zero) and – (minus) keys are used to change the currently displayed
position to a different value. The 0 key forces the unit to display 0. Momentarily
depressing the + key increments the current position by one unit of measurement.
Momentarily depressing the – key decrements the current position by one unit. Pressing
and holding the + or – keys will cause the displayed position to change continuously.
Holding down the key will cause the amount of change to speed up. This allows for quick
adjustments over a range of large values. These keys can be “locked out” to prevent
accidental offset or zero entries. (See Programming Parameter Pr3)
Digital Display Functions
Lock Mode
The user can “lock-out” the position offset adjustment functions (+, -, 0 keys) to prevent
accidental changes of the current displayed position. To activate the lock mode, press
and hold the ON/OFF key and then momentarily press the MODE key. The word LOCK
on the LCD display will turn on or off with each lock/unlock operation. When the LOCK
symbol is displayed, the +, - and 0 keys will not change the displayed position. On
Displays with an auxiliary keypad: ABS and INC modes have independent lock
operations. (See Programming Parameter Pr3. Factory default is Enabled.)
Segment Offset Adjustment
For scales that are longer than 430mm (17 inches), multiple scale pattern segments are
installed end-to-end on the aluminum extrusion. This provides a quasi-absolute
measurement capability in which the readhead can calculate its position on any individual
scale segment but cannot determine which particular segment it is on. To solve this
problem, the Digital Display tracks which scale segment the readhead is on by detecting
the “splice” between one segment and adjacent segments.
In certain situations, the crossing from one segment to another may not be detected by
the display. This may occur if the readhead is disconnected from the digital display and
then moved along the scale to another segment. It may also occur if the readhead is
moved too quickly between two segments. (Maximum slew rate is 400mm/sec, 15in/sec)
If the segment tracking count is incorrect because of one of the above situations, the user
can re-adjust the display to correct the error. This adjustment is referred to as the
Segment Offset Adjustment.
To add one segment value (430.08mm) to the displayed value, hold the MODE key and
then momentarily press the + key. The displayed position will increase by 430.08mm
(16.933 inches). To subtract one encoder segment from the displayed value, press and
hold the MODE key and then momentarily press the - key. The displayed position will
decrease by 430.08mm.
(See Programming Parameter Pr1 and SCALES in Section 1 of this manual for
additional information. Factory Default is set to Enable this function.)

Offset Addition
Offset addition allows the user to preset up to 3 different distances that are then added to
the Digital Displays position when selected. This allows the user to quickly switch
measurement modes from one reference point to another. To utilize the offset addition
feature, programming parameter Pr10 must be set to 1. The display will then flash one of
“offset” numerals 1, 2, 3 or 4 located in the upper left corner of the LCD. Offset 1 is the
ABS position with no offset addition. Offset 2 is the ABS position with parameter Pr11
(Offset Addition 1) added to it. Offsets 3 and 4 have similar functions with parameters
Pr12 and Pr13 added to the ABS position respectively.
To move from “Offset” 1 to 2, momentarily press the F1 key. Each depression of the F1
key advances to the next offset. After offset 4, the display will move back to offset 1.
(See Programming Parameters 9, 10, 11, 12 and 13. Factory default is Disabled.)
Limit Mode
The digital display will show either “ LL “ for Low Limit or ” UL” for Upper Limit if a preprogrammed upper or lower reading is encountered. Upper and Lower limits are set with
programming parameters Pr16 and Pr17 but are only active if Pr14 is set to 1. Display
toggles between current position display and "LL" or "UL". The position is shown for 2
seconds and the "LL" or "UL" is shown for 2 seconds. This continues as long as a limit
has been exceeded. Limit monitoring is always active, even in programming mode.
Numerous Programming parameters, including Offset Addition and Limit mode indicate a
‘factory default set in inches’. The equivalent offset/limit value in mm or cm is applied if
you switch the MODE of display to mm or cm. ie These parameter values take on the
unit of measurement MODE (mm, cm or inches ) active when programming is entered.
Scaling
All Series 950 Digital Displays have the ability to “scale” the actual measurement.
This function is useful when the actual measurement must be multiplied or divided before
being displayed. Care should be taken when using this function since invoking it will
cause the unit to display a reading different than the actual measured or traversed value.
This function is set using Programming Parameter Pr7. The Factory Default is set to
1.000 - No Scaling
Changing the Batteries
A low battery indicator will appear in the lower left corner of the LCD display when new
batteries are needed.
To change batteries remove the screws in the upper right and lower left corners. Pull the
cover off. Remove the old batteries. Reinstall new AA Alkaline batteries, noting the
proper orientation. Replace the cover and tighten the screws.
CAUTION:
DO NOT BEND BATTERY CLIPS!
THESE CLIPS ARE DESIGNED TO BE LOOSE WHEN THE CASE IS OPEN AND WILL COMPRESS AND SECURE THE
BATTERIES IN PLACE WHEN THE CASES ARE SCREWED TOGETHER.

Auxiliary Keypad
ABS - INC
The Digital Display has two measurement “indexes”. One is referred to as ABS and the
other is INC. The ABS measurement setting is designed to allow the user to set a
current position on the display referenced from a fixed or known position such as a saw
blade, or stop. The INC measurement setting is designed to take relative distance
measurements from one arbitrary point to another. The systems operate independently
allowing separate position offsets to be programmed. The ABS position of the measuring
system is not lost when using the INC settings.
ABS Mode – The ProScale automatically enters ABS mode when power is first applied.
This is indicated by the ABS symbol in the upper left corner of the display. While in the
ABS mode, all position measurements are related to the current system reference point.
To enter the INC mode, momentarily press the ABS/INC button.
INC Mode – While in the INC mode, the INC symbol is shown in the upper left corner of
the display. When the INC mode is initially entered, the displayed position will change to
reflect a new reference point at the current position of the readhead. This is typically a
position of zero (0) but may be changed by using the + or - keys to provide an offset.
Moving the readhead in either direction will display the distance moved from the initial
INC starting point (plus any offset). To complete another incremental measurement from
the new position, momentarily press the ABS/INC key. The display will again change to
0 (or the previously programmed offset). To return to the ABS mode, press and hold the
ABS/INC key for approximately 3-4 seconds.
HOLD
The Digital Display provides a feature that allows the displayed position to be “frozen” in
time while the readhead is moved from its measuring position.
This allows
measurements to be captured on the display and held for later viewing regardless of the
current readhead position. To activate the HOLD mode, momentarily press the HOLD
key. The HOLD symbol will be shown in the upper left corner of the display. The
currently displayed position and selected key presses will be frozen at this point. To
release the HOLD feature, momentarily press the HOLD key again.
Mitutoyo America Corp. - ProScale Series 950
21 of 36
MONitor
The Digital Display has the ability to monitor a position to detect position drift or
measurement variance. To activate the monitoring mode, position the readhead to the
desired location and momentarily press the MON key. The MON symbol will flash on the
display to indicate that the position monitor mode is active.
If the readhead moves outside the programmed tolerance the displayed reading flashes,
indicating a drift condition. When the readhead is moved back within the programmed
tolerance, the displayed reading will stop flashing.
To exit the monitor mode, momentarily press the MON key. The MON symbol will stop
flashing and the currently displayed position will also stop flashing.
NOTE: Position monitor mode can only be activated while in the ABS measuring mode.
If the ABS/INC key is depressed while monitoring, the position-monitoring mode is
automatically exited.
The display can be programmed to automatically enter or exit the MONitor mode based
on elapsed time or movement of the encoder.
If the programmable auto monitor is enabled (Programming parameter Pr19 set to 1), the
Digital Display will automatically enter monitor mode after either 30 or 60 seconds of no
encoder motion. If the programmable auto monitor is disabled, the ProScale will
automatically exit monitor mode if the encoder is moved beyond a programmable
distance from the monitored position. This option, in conjunction with auto monitor
activation, allows the ProScale to be kept in monitor mode without manually pressing the
monitor key.
(See Programming Parameters 19,20, 21. Factory default is OFF.)
SEND
The Digital Display provides an output port that can be used to send measurement
information to a compatible SPC device such as a printer or data acquisition unit. After
connecting the SPC device to the 10 pin connector on the display, the user may initiate
the data transmission by momentarily pressing the SEND key. This signals the SPC
device to acquire the data from the digital display.
Pressing the SEND key displays “ Snd ” on the display for 1 second to show activation of
the send function (even if no SPC device is attached to the ProScale).
The data format and connector style of the ProScale SPC output is the same as other
Mitutoyo SPC enabled products and can be interfaced with most available SPC products
including multiplexers, RS232 converters and PC plug-in boards. Data from the ProScale
is sent to the SPC connector in either millimeters or decimal inches, whichever is
currently displayed on the LCD.
If no SPC device is attached to the display, the SEND key has no other function.
See Section 6 Accessories for interface and data acquisition products descriptions.

Programming
Several functions of the digital display are user programmable. The following instructions
describe what features are available and how to change the system’s factory defaults to
customize the display for your application.
The keys pictured have multiple functions. Timing, which is how long a key is depressed,
and the combination of the keys pressed is important. This manual uses the term
‘”momentarily” to describe a key press of typically less than 1 second. Whereas “press
and hold” is used imply a key press of typically longer than 1.5 seconds. As an example;
when using a PC keyboard to type a CAPITAL letter you would “press and hold” the
SHIFT key and “momentarily depress the appropriate letter key.
The “function” associated with the key(s) pressed is executed on the key RELEASE, not
the key DEPRESS. This is important since some keys execute different functions based
on how long they are depressed. These key operations, once tried, quickly become
intuitive.
To enter programming mode, press and hold the MODE key and then momentarily press
the 0 (zero) key. The MODE key must be held for approximately 1 second before the
depression of the 0 (zero) key.
Once you are in the Programming Mode, momentarily pressing the MODE key will
advance through the Programming Parameter list.
To step backwards in the Programming Parameter list press and hold the ON/OFF key
and momentarily press the MODE key.
Momentarily pressing the + (plus) key while displaying a Programming Parameter will
increase the parameter setting.
Momentarily pressing the - (minus) key while displaying a Programming Parameter will
decrease the parameter setting.
Momentarily pressing the 0 (zero) key while displaying a Programming Parameter will
revert the parameter to its factory default setting.
To exit programming mode, press and hold the MODE key and then momentarily press
the 0 (zero) key.
NOTE: The display will automatically exit programming mode after 60 seconds of no key
activity.

How long a key is depressed, and the combination of the keys pressed is important. The
term (Momentarily) describes a key press of typically less than 1 second. Whereas
(Press & Hold) is used imply a key press of typically longer than 1.5 seconds.
For example: When using a PC keyboard to type a CAPITAL letter you would “press and
hold” the SHIFT key and “momentarily” depress the LETTER key.
In addition, a key(s) “function” is executed on the key RELEASE, not the key DEPRESS
of that key(s). This is important since some keys execute different functions based on
how long they are depressed. These key operations, once tried, quickly become intuitive.

Frequently Asked Questions
What does “no Enc” mean?
If the readhead is off the scale, or the readhead cable is unplugged from the digital
display, an “no Enc” will appear on the display. To clear error:
1.
Be sure the readhead is on the scale.
2.
Unplug the connector from the display for one second.
3.
Reconnect the readhead cable to the digital display.
The battery clips seem to be very loose. Is this normal?
Yes. DO NOT attempt to bend these clips or wedge anything between them and
the case. These clips are designed to expand when the two case halves are
screwed together.
Can I mount the scale/readhead without the flex link/guide clip?
The flex link and guide clip serve to provide an accurate method of transferring the
movement of the moving part to the readhead or scale, while also absorbing any
stresses that may occur. If they are not used, the warranty could be voided.
The display reads numbers but they seem to be random.
Be sure the readhead is oriented correctly on the scale. One end of the scale is
black. Be sure that the arrow on the readhead is pointed in the correct direction.
The display does not change as the scale/readhead moves.
The display is in the HOLD mode. Press & release the Hold button.

Abbe Error
Abbe error is a condition that may not be visible to the human eye, but will affect linear
measurements. Be sure to take precautions when installing ProScale in order to eliminate
the possibility for Abbe error.
Abbe error refers to a linear error caused by the combination of an angular error and a
dimensional offset between the sample and the measuring system. It is important to
understand that the information the encoder is providing is only the position of the
readhead on the scale. To illustrate this, see the figure, which shows a linear
measuring device. (The apparent distortion in the measuring device is intentional - for this
example - to show the measuring device with a curvature in its mounting.)
Suppose the curvature in the figure is sufficient to produce an angle of 40 arc-seconds. If
the measuring device moves 10 inches, the probe will be found to have moved 10.0039
inches, resulting in an error of +0.0039 inches. Abbe error could be lessened by moving
the measuring system closer to the sample. This effectively solves one half of the Abbe
error problem (offset) and leaves only the angular mounting problem to be solved.
Angular error can best be countered through proper design and placement of the linear
scale. Sources of angular error include:
1.
2.
3.

ACCESSORIES
ProMUX-3™
The ProMUX 3 is an easy to use hardware interface device providing communication and
control of one to three ProScale ABS linear encoders from a user provided PC or PLC.
Supplied are two separate components. First is the ProMux 3 interface unit and second
is a low voltage plug-in power supply. The user must provide the host PC or PLC and a
standard DB-9 serial cable (male to female).
Uses for the ProMux 3 include axis position measurement on XY or XYZ quality control
measurement tables, machinery position control (NON-CNC), tooling measurement
devices and the like.
ProMUX-4™ & ProMUX-8™
The ProMUX-4 and ProMux-8 series of linear encoder multiplexers are designed for OEM
and system integrators for use in acquiring setup positional information (non-CNC) on
industrial production machinery.
The multiplexers interface directly with ProScale absolute linear measurement encoders.
These systems provide linear measurement ranges from 100mm to 6 meters depending
on the model.
ProMUX 4/8 multiplexers communicate with a host PC or PLC via RS-232 or RS-422
serial interface. Various baud rates are supported from 9600 to 115200. Up to 15
multiplexers can be connected to the same communications bus when utilizing the RS422 serial interface.

Pro RF
The Pro-RF™ system consists of a base module and a remote module that communicate
over a bi-directional RF interface.
The Remote module provides the data acquisition functions.
It accepts 1 ProScale (Mitutoyo) SPC output as input and relays the information via RF
link to the Base module.
The Base module communicates to a host PC via RS-232 operating at 57,600 Baud.
The system can support up to 32 remote modules up to 100 meters away for each base
module.
Analog Interface Unit
The Analog Interface Unit (AIU) is designed to provide an analog signal output that is
proportional to the current position being displayed on a ProScale linear measurement
system. The interface provides a DC signal range from 0 to 5 volts or 0 to 10 volts
depending on configuration. This offers a simple integration between a ProScale™ linear
measurement system and a PLC or other process control system.
The interface incorporates a 12-bit Digital-to-Analog converter to generate the analog
output. This provides 4096 discrete steps of resolution over the configured measuring
range. This can offer a measurement displacement resolution of .001” over a 4-inch
range of motion.
