AVL (Air Ventilation Logging)

The Fresh Air Exchange Recorder (AVL) detects vent disk movement and automatically displays a value in the LCD display for values of 0 to 125 m3/h. For settings greater than 125 m3/h the technician must set the AVL Open Value to match the notched setting on the Fresh Air Exchange Vent.

AVL must be selected under the CONFIGURATION/OPTIONS/CONTROLLED ATMOSPHERE (CA) and FRESH AIR OPTION must be mounted under CONFIGURATION/OPTIONS/FRESH AIR OPTION for AVL to be active or visible.
