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.
