The Basics of ColorFlex EZ Operation

Commands are given to the ColorFlex EZ using the five buttons on its button pad, and
instructional prompts and measurements are displayed on the 320 x 240 pixel on color liquid
crystal display (LCD) screen.
When an item is to be measured using the ColorFlex EZ, the area of interest should be placed
flush at the sample port with the side of the sample to be measured toward the instrument.
The sample must completely cover the sample port.
When the read command is given using the button pad, the xenon flash lamp illuminates the
sample, and the light reflected into the detector by the sample is evaluated. The calculated
measurement is then shown in the display. Up to 2000 readings and 250 product setups may be
stored in the ColorFlex EZ's memory.

The Button Pad and LCD Display

The five buttons on the button pad can be loosely defined as the LEFT, RIGHT, UP, and DOWN
buttons, with the GO (lightning bolt ) button located to the right of the arrows. These buttons
perform slightly different functions depending on the current operation. Consult the miniature
map of the button pad shown at the bottom of the LCD display for the relevant definitions of
the buttons at any particular time.
Figure 2. Main Menu Key Pad
Across the top of each measurement screen are numbers indicating (left to right) the Datalog
number for this reading if it was saved to the ColorFlex EZ's memory, and the number of hours
and minutes since the instrument was last standardized.

Menus and Prompts

All ColorFlex EZ functions may be accessed through its main menu. The main menu commands
lead to prompts (such as for standardization and reading), setup screens (for product setup and
global options), or an additional menu (such as the Diagnostics, Saved Readings, and Setup
Maintenance choices), depending on the function requested.
When RETURN is shown as an available button command on the MAIN MENU screen, choose
RETURN to go back to the last screen used before the instrument shut down.
