Mount the sensors according to the described measurement method with the appropriate distance
and apply sufficient coupling gel to the sensors. The meter should now be able to receive a
signal and display this via the quality indicator. If the quality indicator is within the green range,
you can continue with the distance setup. If there is no signal or a poor signal, check the settings
again and follow the preparation steps described in chapters 6.1 and 6.2.
Now adjust the distance of the sensors so that the distance indicator is as central as possible
within the green area. A good setting is shown below.

After setting the distance, the meter is ready for operation and the measurement can be made.
Since the zero point may be shifted depending on the measuring conditions (installation, pipe
material, etc.), it is possible to reset the zero point in the installation view. To do this, it is
necessary to ensure that the liquid in the pipe does not move!
In the installation view, press and hold the OK key until the confirmation dialogue opens and
confirm the setting of the zero point. While the meter is determining the zero point, a waiting
dialogue is displayed. After this has closed, the zero point is set.

In order to carry out a heat quantity and heat output measurement, it is also necessary to
connect the temperature sensors to the device and attach them to the corresponding measuring
locations. Temperature channel 1 must be attached to the warmer measuring location (e. g. the
feed line of a heating system) and channel 2 to the colder measuring location (e. g. the return
line of a heating system).
