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

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.

SECTION 3 P
ROSCALE MODEL 250
ProScale Model 250
A General Purpose measuring system with nine standard measuring ranges from
0-300mm (12in.) up to 0-6m (20ft.).
Model 250 systems use ABS style scales, ABS style readheads, and any of the available
digital displays. Neither the scale nor readhead are compatible with any Accurate
Technology incremental technology measuring systems.
ProScale Model 250 is easy to install. By following the basics of good installation,
reliable, error-free operation is assured. ProScale M250 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.
Note: If a custom kit was ordered which contains instructions for installing ProScale on a
specific product, follow those instructions rather than the general instructions here.

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.)
2. Determine an appropriate mounting location for the system. Most applications of
the Model 250 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 on next page).
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.
Note: Failure to use the guide clip could void the warranty.
4. 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
Note: If any other mounting method is used, observe the following:
A. Do not drill through the green portion of the scale at any point over which the
readhead will travel.
B. Do not mount the scale so the mounting hardware interferes with the
movement of the readhead.
