INTRODUCTION
The PR-655 and PR-670 SpectraScan are the newest additions to the already world renowned
SpectraScan colorimeter series of instruments. These unique, portable battery powered instruments
utilize fast-scanning photo diode arrays, a 3.5” color touch screen display, and AutoSync®for
automatically synchronizing to the source refresh rate insuring the utmost accuracy. Other features
include an external trigger port allowing remote measurement activation from a push button or
peripheral device, a Secure Digital (SD) card for measurement storage, and a long lasting rechargeable
Lithium-ion (Li-Ion) battery for more than 12 hours of operation. The PR-670 adds to the PR-655 with
four automated apertures, two measurement sensitivity modes (Standard and Extended), and four
measurement speed modes (Normal, Fast, 2X Fast and 4X Fast).

LCD SCREEN
The PR-655/670 features an on-board, 3.5” high resolution, full color touch screen LCD display. The area visible
to the user is called the active area. The active area of the LCD display contains the graphical user interface of
the PR-655/670. All setup options and measurements including spectral and CIE graphs can now be controlled
and viewed directly on the vivid color display.
SYSTEM INFORMATION
The system status screen, is displayed when the unit is powered on, and shows system information such as serial
number, calibration due date, firmware version, and instrument bandwidth. This screen can be viewed at any

The flow of the menu navigation on the PR-670 is similar to that of a tree structure. In a tree structure there
are roots and from the roots exist branches (sub menus), indicated by the following icon ( ) which have more
branches or end nodes (leafs). Traversing back to the root is as simple as clicking on the back ( ) icon,
located at the bottom right corner of the GUI.
The following example depicts the tree structure mentioned, by navigating to the Date & Time setup screen
from System Menu.
