SECTION 1 INFORMATION GENERAL Introduction ProScale™ digital measuring systems are affordable precision electronic devices for making linear measurements with speed and accuracy. ProScale consists of a scale, a readhead (or encoder) and a digital display. It uses capacitive encoder technology, the same technology used in digital calipers. Because ProScale is a solid-state electronic device there's very little to wear out.

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. The READHEAD, or encoder, contains a 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 (10µm / .0004in).
Scales Absolute An (ABS) Absolute measuring technology system measures its actual position by reading a pattern which is unique at any given location over a segment length. The maximum length of a ProScale absolute segment is 430mm (16.932 in.). The segment must then repeat. Consider the illustration above to represent a ProScale approximately 50 inches long. There are three absolute segments joined together. Within each segment the system is absolute.
Incremental Simply stated, an Incremental system measures the distance it has traveled relative to a starting point. Incremental style scales have a repeating “bar” pattern on a green laminate. There should be a “SPLICE” approximately every 570mm (22in.). Incremental scales may be shortened if needed. Incremental Style Pattern Scales used on Absolute and Incremental systems should never be mixed. Avoid drilling through the green portion of any scale.
