5.2.7. Set the compensation temperature
➢
Go to
"Temp Compens"
line then press
OK.
➢
Set the temperature with arrows then press
OK.
This temperature must be between
-20 and 80°C.
5.2.8. Activate or deactivate the standardised airflow
The standardised airflow allows to have a calculation of airflow as per DIN 1343 standard.
➢
Go to
"Standard airflow"
line then press
OK.
➢
Select
ON
or
OFF
with up and down arrows then press
OK
.
When standardised airflow is activated,
"NORMO"
indication is shown on screen on the left of time.
5.3. Activate or deactivate air velocity and airflow
It is possible to activate or deactivate measurement in air velocity and/or airflow.
➢
Press
"Menu"
.
➢
Go to
"Measurement"
with left and right arrows then press
OK
.
➢
Go to
"Airflow"
or
"Air velocity"
then press
OK
.
➢
Select
ON
or
OFF
then press
OK
.
5.4. Use the Matrix grid
The Matrix grid is designed for the air velocity measurement on any types of celling vents or diffusers with a large useful
area.
To use the DBM610 in Matrix grid mode, place the grid on the telescopic pole and add the positioning struts that will be
against the celling. Struts are available in 3 different lengths:
•
3 x 5 cm
•
3 x 15 cm
•
3 x 25 cm
These struts allow to remain parallel to the celling. The length of the struts allow to be more or less distant from the celling,
it can be useful in case of high air velocity. Indeed, the air velocity decreases as soon as we keep away from the celling
vent.
To connect the silicone tubes:
➢
Ensure that each silicone tube is connected correctly. For example, the white one connected on the
“+”
sign of the
micromanometer and on the
“+”
sign of the Matrix grid and the black one connected on the
“-”
sign of the
micromanometer and on the
“-”
sign of the Matrix grid
5.5. Perform averages
The micromanometer can perform 3 types of averages: automatic average, point/point average and automatic point/point
average.
➢
Press
"Moy/Avg"
button.
➢
Select the type of required average then press
OK
.
5.5.1. Automatic average
This function allows the calculation of the average value measured by the device in a selected time interval.
First, select
"Auto average"
, the device displays measurement screen.
➢
Press
OK
to launch measurement
.
The device displays measured values and measurement duration.
➢
Press
OK
to stop measurements and get results.
➢
Press up and down arrows to get to results of different parameters.
➢
Press
"Save"
button to save dataset or
Esc
to cancel and back to measurement screen.
