5.1 Using the Uf 811
The Uf 811 has a screen and a keypad which can be used to configure and view the measurements as they
are taken. LEDs indicate the status of the measurement and of the flow meter communication.
5.1.1 Operating mode
Uf 811 flow meters operate in 3 modes (3 types of screen):

Measurement mode (flow rate, speed, gain, quality index, etc.) which includes all the measurement
screens,
 Configuration mode (section description, logger, etc.) which includes all the configuration screens,
 Echo Display mode (portrait, zoom) which includes all the echo display screens.
5.1.2 Keypad
 Changing from one type of screen to another is done by using the "Fn" (for Function) key. This
"Fn" key in particular is used to enter
configuration
mode. The

and

keys allow the user to
browse through the menus for this mode.
 A long press on the "Fn" key, or allowing approximately 1 minute to pass without using the keypad,
returns you to
measurement
mode.
 Within a menu, the

and

keys are used to change page. These keys may also have a contextual
function which in this case will be shown at the bottom of the screen page, such as that of selecting
the measurement mode screen which is displayed by default.
 After powering on the Uf 811, the screen displays the page which has been selected as priority. To
choose this "default" screen, select and validate it by pressing the "
B " key in
measurement
mode.
 To scroll through the measurement screens, use the



keys.
 To access the other menus, press the "Fn" key, then successively press the

key, or browse using
the

and

keys.
 To enter a menu, press

or

. To change page, press " A " or " B ". To change a row, select it using

or

and change the value using

or

.
 If no key is pressed for approximately one minute, the Uf 811 automatically returns to measurement
mode and to the display chosen as priority using "B".
 For a given parameter, the value to be applied is defined using the

(increase) and

(decrease)
keys. An extended press on one of these two keys accelerates the increase or the decrease.
