Page 2: Introduction
Temperature is measured in °C or °F, air veloc- ity in m/s or fpm and air flow in l/s, m3/h or CFM. SwemaAir 5 has a built in barometer that with the measurement of temperature makes it possible to compensate for correct air density. -
Page 3: Technical Data
When starting the instrument (ON/OFF-button), the display shows the battery voltage, firmware version and calibration date. The instrument enters measuring mode after a couple of seconds. SwemaAir 5 will start in the same measuring mode it was set to before turned off. -

The dis- play will show which note number the measurement is saved as (i.e. n3 = note 3). To erase the measurement from the volatile memory press Clear. - Page 5 Air Flow (l/s, m /h or cfm) SwemaAir 5 can measure air flow via three different methods. Swe- maAir 5 measures air flow in: • Circular ducts with a given diameter • Rectangular ducts with a given Height x Width •...
