Main Screen
The FU-ES features nine main screens. The H09 Home Page function allows selection of the screen displayed at startup. Detailed instructions for H09 operation are provided at the end of this chapter. There are also two debugging screens, which are displayed when H10 is enabled.
The FU-ES display consists of an upper LED display and a lower LCD display. The LED display shows real-time flow data (up to five digits). The LCD display changes content according to the main screen selected.
When the main screen is displayed in green backlight, the four buttons function as follows:
Blue Button (leftmost): No function
Gray Direction Buttons:
Left Gray: Page navigation
Right Gray: Page navigation

The first line of the LCD shows the velocity unit (m/s), the second line displays Velocity, and the third line shows the flow signal on the lower left and Setup on the lower right, indicating that pressing the orange button switches to the Settings screen.。
Velocity units can be adjusted in B04 Velocity Unit.
Screen 3: Total
Displays total accumulated flow. The LED display shows data (up to 5 digits). The first line of the LCD shows the total flow unit (L), the second line displays Total Flow, and the third line shows the flow signal on the lower left and Setup on the lower right, indicating that pressing the orange button switches to the Settings screen.
Total flow units can be adjusted in B03 Total Unit.
Flow in Simulation Mode is also included in the total flow.
Screen 4: Flowrate <Large>

Velocity units can be adjusted in B04 Velocity Unit.
Screen 6: Total <Large>
Displays total flow with enlarged digits for easy viewing. The LED display shows data (up to 5 digits). The LCD large digits show Total Flow, POS at the bottom indicates forward direction, and the lower right shows the flow unit (L). Pressing the orange button at the lower right switches to the Settings screen.
Total calculation method can be adjusted in C01 Total Method: POS (Forward), NET (Net), NEG (Reverse), and total flow units can be adjusted in B03 Total Unit.
Flow in Simulation Mode is also included in the total accumulated flow.
Screen 7: Dosing
Used for batch or quantitative control (Dosing). The LED display shows data (up to 5 digits). The first line of the LCD shows the Dosing Reset Time, the second line shows Total Flow, and the third line shows the flow signal on the lower left and Setup on the lower right, indicating that pressing the orange button switches to the Settings screen.
