Page 6: General Information
ECTION ENERAL NFORMATION Introduction DigiScale is a general purpose linear measuring system It consists of three major parts: a , an and a SCALE ENCODER DIGITAL READOUT DigiScale is an ideal choice for most measuring requirements up to 60 inches where affordable digital precision (better than a tape measure) is desired. -

40 to 110 F Slew Rate: 60 inches/second Encoder cable: 72 inch * MEASUREMENT range is approximately 4 inches shorter than the PHYSICAL length of the aluminum scale extrusion. Accurate Technology DigiScale Models 18 & 28 User Manual Page 7 of 36... -
Page 8: About Digiscale
About DigiScale All DigiScale systems consist of a (or track), an , (or SCALE ENCODER readhead) and a (DRO). DIGITAL READOUT Scale DigiScale Models 18 & 28 The scale consists of a series of conductive patterns bonded to an aluminum extrusion. -
Page 9: Installation
Be sure connections are secure or inaccurate readings could Connector Link result. Plug the encoder cable into the readout. Accurate Technology DigiScale Models 18 & 28 User Manual Page 9 of 36... - Page 10 Stationary Scale installation If your application is better suited for the scale to be held stationary and the encoder moved along it during a measurement, you should use the Guide Clip to capture the encoder and move it along the scale (see illustration). Attach the scale to a fixed point in your application using the included screw.

Page 18: Operation
Operation Readout Keys TIMING The keys pictured above, are found on all Digi readouts, and some of them 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 shorter than 1 second. -
Page 19: And - Keys
If the readout decrements (reduces or goes negative) when it should be incrementing (increasing or going positive), the readout will need to be re-programmed for your application. See Section 3: Programming, Programming Parameter Pr2. Accurate Technology DigiScale Models 18 & 28 User Manual Page 19 of 36... -
Page 20: Incremental Measurements
INCREMENTAL MEASUREMENTS The readout has two measurement modes, or indexes. One is referred to as ABS or Absolute, and the other as INC, or Incremental. The absolute measurement mode allows the operator to read the current position of the encoder referenced from a fixed or known position-usually zero. The incremental mode allows the operator to make relative distance measurements from one arbitrary point to another. -
