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

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.

Do not mount the scale so the mounting hardware interferes with the

movement of the readhead.
