Switching on and taking measurements

When the device is switched on, an ID string is shown.
On switching the device on using the ON/OFF button, just press the “Menu” or “Battery” buttons to switch to measurement mode, where the current

flow rate read by the sensor is displayed. The sensor must be connected to the device in order to take a measurement.

When measurement is underway, the following appears on the display:

Q = 610 [ l / h]

The flow rate symbol is shown followed by a number and the unit of measurement in square brackets. The type of medium is shown on the

second line of the display.

If the flow rate measured is too low (less than 300 l/h), if the sensor is not connected or inserted properly, the device will not be able to measure

correctly and a flow rate of 0 will be shown.

The LCD display shows flow rate during measurement,

configuration menus and other information needed for the correct

use of the device.
To switch on the device, just press and hold the

●

on button until

words appear on the display. To switch the device off, just press

and hold the on button

●

until all words on the display disappear.

If no keys are pressed for 4 minutes, the device automatically

switches off even if the sensor is still connected: this prolongs the

life of the internal battery.

To extend battery life, a system has been included that switches

the device off after the Vortex sensor cable has been connected or

disconnected.
Pressing the “Light”

●

button switches on or off the display backlighting, enabling it to be used in dark places with no lighting. The backlighting

is switched off automatically after 1 minute to prolong battery life.
Pressing the

○

button opens and allows to browse the configuration menu. On exiting the menu page, it returns to the measurement display.

Pressing the

●

button from the measurement screen shows the status of the device’s internal battery. To go back to the measurement screen,

press the

●

button again.
