4. Using DBM610 in airflow meter mode
4.1. Starting up
When the airflow meter is correctly set and the housing mounted on the base,
press
On/Off
button:
The device directly displays the data below (see photo):
•
airflow
•
delta pressure
•
temperature
The solenoid valve is active and flaps every second.
4.2. Configure the airflow meter
➢
Press
"Menu"
.
➢
Press
"Left arrow"
or
"Right arrow"
key until reach
"Configuration"
.
➢
Press
"OK"
.
The sub-menu
"Configuration"
appears with following data:
•
Correction coefficient:
allows to set the correction coefficient
•
Units:
allows to set unit for airflow, pressure and temperature
•
Damping:
allows to smooth the measurement and avoid unwanted
•
Standard airflow:
allows to activate or not the standardized airflow as per DIN1343 standard
4.2.1. Set the correction coefficient
➢
Go to
"Correction coef"
line then press
OK
.
➢
Select the required correction coefficient with up and down arrows then press
OK
.
Screen displays the selected coefficient. It is possible to modify it with arrow keys.
➢
Press
OK
to validate and back to
"Configuration"
menu.
4.2.2. Set measurement units
➢
Go to
"Unit"
line then press
OK
.
➢
Go to the required line (airflow, temperature or pressure) then press
OK
.
➢
Select unit with up and down arrows then press
OK
.
Available units are:
•
Airflow:
m
3
/h, L/s, cfm
•
Pressure:
Pa, mmH
2
O, mmHg, inWg
•
Temperature:
°C, °F
➢
Press
Esc
to quit
"Units"
sub-menu
and back to
"Configuration"
menu.
4.2.3. Set a damping
➢
Go to
"Damping"
line then press
OK
.
➢
Select the required coefficient (from 0 to 9) then press
OK
.
4.2.4. Activate or deactivate standardised airflow
The standardised airflow allows to have a calculation of airflow as per DIN 1343 standard.
➢
Go to
"Standard airflow"
then press
OK.
➢
Select
ON
or
OFF
with up and down arrows then press
OK
.
When standardized airflow is activated,
"NORMO"
indication is shown on screen on the left of time.
