5.1 Using the UF 831
The UF 831 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
The flow meters operate with 3 different types of displays:
 “Measurement” displays/mode (flow, quality…),
 “Settings” displays/mode (description of section, logger...),
 “Echo” displays/mode (landscape, zoom…).
5.1.2 Keypad
The Fn (for Function) key is used to switch between displays/modes. This Fn key is used in particular to
enter the “settings” mode.
The < and > keys are used to browse through the menus of this mode.
A long press on the Fn key, or allowing approximately 1 minute to pass without using the keypad, returns
you to the “measurement” mode.
