The Basics of ColorFlex EZ Citrus Operation
Commands are given to the ColorFlex EZ Citrus 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 Citrus, the sample 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 Citrus ’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 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 Citrus
’s memory, and the number of
hours and minutes since the instrument was last standardized.
Menus and Prompts
All ColorFlex EZ Citrus 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.
