11.2.3.3 Leak flow volume delay
Activation of the leak flow volume can be delayed. The value
can be set with the menu.
Leak flow volume
Leak flow volume x 0.75

11.2.3.4 Basic calibration
NOTICE
▶ The "Basic calibration" function enables an optimal adapt-
ation to medium-specific properties. By performing this
function, the product runs through an internal parametriz-
ation and saves the relevant parameters independently.
This process can take up to approx. one minute.
NOTICE
Important:
▶ The device must be filled with liquid and there must be no
flow so that the adjustment can be correctly executed.
▶ If an error has been detected during the calibration, for
example, because the device is not filled, "Error" appears
on the display. If the calibration has been performed suc-
cessfully, the message "Carried out" is displayed.
11.2.3.5 Water
For this menu item, the correction values of the medium mat-
rix are written back to the water value.
11.2.4 General settings
11.2.4.1 Daily quantity reset
The counted daily quantity of the product can be reset using
this function. For an operating example of the quantity reset,
see annex.
NOTICE
Important:
▶ Unintentionally deleted counter readings cannot be re-
stored. Counting begins at 0 again after the reset.
11.2.4.2 Hysteresis limit value
The limit values can be equipped with a hysteresis. This is to
prevent frequent switching of the outputs if a flow is near a
limit value.
High set point = 110 ml/s Hysteresis = 20 ml/s Filter = off
