Programming Parameters are listed below. Values in [ ] are the available range of values 
that can be programmed for that entry. Factory defaults are shown in bold. 
Pr0 – Encoder Direction  [0,1] 
  Change value to reverse the direction of measurement readings. 
Pr1 – Enable/Disable Segment Offset    [0, 1] 
0 = For ABSOLUTE scales shorter than 430mm, (16.9in). ALL Incremental scales 
  1 = For All ABSOLUTE scales longer than 430mm, (16.9in). 
Pr2 – High Speed Readhead  [0, 1] 
0 = Normal Readhead  
1 = High Speed Readhead 
Use this setting only if instructed by special instructions included with High Speed 
Readheads. A setting of 1 will impact battery life. 
Pr3 – Enable/Disable the +, - and ZERO keys  [0,1] 
  0 = Disables operation of Zero, + and – keys (Display will be in Lock Mode). 
  1 = Enables operation of Zero, + and – keys. 
Pr4 – Display Resolution  [0, 1, or 2] 
Sets the displayed resolution in decimal mode. (No change in fractions mode.) 
0 = Reduced resolution  Inch = xxx.xx  MM = xx.x 
1 = Normal resolution    Inch = xxx.xxx  MM = xx.xx 
2 = Increased resolution  Inch = xx.xxxx  MM = xx.xx  (Inch mode only) 
Auto scaling will allow measurements of over 100 inches when in high resolution. 
Measurements over 100 inches will automatically be reduced to 3 decimal places. 
Pr5 – Metric Display Units  [0, 1] 
Controls whether the measured value is displayed in millimeters or centimeters 
when in metric mode. 
0 = millimeters 
1 = centimeters 
Pr6 – Disable Fractions/Inches  [0, 1, 2] 
0 = All measurement modes (millimeters or centimeters, inches and fractions) 
1 = No Fractions.  Only decimal inches and metric units* will be displayed. 
2 = Only Metric.   No Imperial (decimal inches or fractions) will be displayed. 
* Pr5 will determine if mm or cm are displayed for metric units. 
Pr7 – Scaling Factor [.001 .. 99.999] Default = 1.000 (No Scaling.) 
The multiplier applied to the measurement. Scaling factors less than 1.000 will 
make the displayed measurement less that the actual measurement. Scaling 
factors greater than 1.000 will make the displayed measurement greater than the 
actual measurement.
