Measuring features
The ND 1200 measures point, line, circle, distance and angle features.
To measure a feature using
backward annotation (See "Select the
desired annotation" on page 31):
U Press the desired feature MEASUREMENT key
U Probe the required points
U Press the FINISH key
Auto repeat
Use auto repeat to measure several features of the same type (such
as a series of circles). Press the desired feature MEASUREMENT key
twice to activate auto repeat. For example, press the CIRCLE
MEASUREMENT key twice to measure a series of circles. When auto
repeat is selected, the Probe feature screen becomes the Probe
features screen. For example, the Probe Circle screen becomes probe
Circles screens as shown below.
Use auto repeat and forward annotation to speed up repetitive
measurements. For example, the measurement of a dozen circles
requires the user to press the CIRCLE MEASUREMENT key before
measuring each circle and press the FINISH key for each
measurement. The same measurements using auto repeat and
forward annotation requires the user to press the CIRCLE
MEASUREMENT key twice before and the FINISH key once after
measuring all 12 circles. Pressing the FINISH key turns off auto repeat.

Examples of measurements are shown in the next few
pages and will use crosshairs to probe points on the 2-D
demo part shipped with each ND 1200.
Examples show feature probing and measurement using
forward annotation with the factory default minimum
points probed for each feature type. The number of
required points for each feature type can be changed in
the Measure setup screen discussed later in Chapter 2:
Installation, Setup and Specifications.
