Selecting the measuring mode
When the device turns on, it is set to
Pressure (Pa)
(channel A, see on the top in the left cell)
.
For
channel B, the last selected setting is set (see on the

Select mode
Q@50 (m³/h)
on Channel B.
“Q”
signifies flow.
In this mode, Channel A measures the building
pressure differential. Channel B displays the
calculated airflow at 50 Pa. The magnitude of this
airflow depends on the size of the flow ring
installed and the speed of the fan.

•
On the DG-1000, the fan model and the flow ring
configuration must be set accordingly.
