SPC (Statistical Process Control)

The data format and connector style of the ProScale SPC output is the

same as Mitutoyo SPC. This is an industry standard that 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.

Accounting for Kerf

When a measurement needs to account for kerf, ProScale makes it easy

to make the measurement without having to perform any calculations.

The following is an example of how to account for kerf on a table saw.

For other instruments in which kerf should be considered, vary this

procedure accordingly.

1. Measure the kerf of the saw blade as accurately as possible.

2. Press the ABS/INC button on the Display to set display to INC.

3. Press the PLUS (or MINUS) key until the kerf measurement is

displayed.

4. Press the ABS/INC button for one second to save this value into the

display's memory.

5. After the first cut, press the ABS/INC button to compensate for kerf.

6. Press the ABS/INC button before each of the following cuts.

7. When finished cutting, press the ABS/INC button for 3 seconds to

view the absolute distance from the saw blade.

Changing the Batteries

To change the batteries, remove the two screws holding the cover to the

base of the display housing. Carefully pull off the cover. Remove the

batteries. Reinstall new ones, noting the proper orientation shown in the

battery compartment. Replace the cover and tighten the screws.

Note: DO NOT ATTEMPT TO BEND BATTERY CLIPS!

Mounting the Display

There are four small mounting holes in the back of the display which may

tapped for M2 or 4-40 screws. The display may also be mounted using

double sided tape or Velcro.
