13 Measurement Operations

Feature Summary
The Everest Ca-Zoom 6.2 System supports five types of comparison measurements.
• Length
• PT-Line (Point-to-Line)
• Area
• Multi-Length (Multi-Segment Length)
• Circle Gauge
• Comparison measurement uses the size of a known object to measure other objects in the same
view and plane.
• Such measurements are made using zoomed or unzoomed frozen or recalled images.
• To aid in cursor placement the optional Parallel Laser accessory provides a reference
measurement on a perpendicular surface. Refer to page 43 for instructions on operating the
laser accessory.
• Although their accuracy is limited, comparison measurements are useful if you want to check
the approximate size of many items quickly. Comparison measurements begin by establishing
a known dimension as a reference scale.
• In the recalled or frozen image, cursors are placed across a known dimension and that dimension
is entered into the system.
