Measurement Scales
You can choose either English or metric scaling for the coordinates you digitize. AccuTab II
applies the required conversion factor before constructing a coordinate format for output.
The numbers appearing in coordinate formats depend on resolution. Table 12 shows how
the resolution settings affect the data in coordinate formats.
To set the measurement scale:
Custom Configuration Menu: Select a resolution in the “Resolution” column of Mode
Options.
GTCO Commands:
1. Send command IN for English or command MT for metric measurements.
2. Send command LR for 100 lpi/200 LPI/10 lpmm, command HR for 1000 lpi/40 lpmm
or command H1 for 4000 lpi/150 lpmm resolution.
Metric example: The distance between two points is 2032 counts in the 40 lpmm binary
format. Each count represents 0.025 mm (from Table 12). Then, 2032 counts x 0.025
mm/count = 50.8 mm.

Digitizing Modes
Digitizing mode refers to the method AccuTab II uses to determine when to output a
coordinate format. Six digitizing modes are available, but only one can be used at a time:
 Point Mode
 Line Mode (sometimes called Switched Stream Mode)
 Continuous Mode (sometimes called Stream Mode)
