3.3 Auto Range Feature
The Accutron IS comes with a unique feature called auto ranging. It is a quick and easy way to install
your setup without measuring your face-to-face distance. To use this feature, you must do the
following:
1. Make sure that all cables and wires are attached and safely secured.
2. Power the Accutron IS.
3. To start the auto range function, enter a value of 0 in the face-to-face menu. This will force the
Accutron IS to begin auto ranging.
4. Save the settings and restart the system.
5. Upon restart, the display will read “Accutron”, followed by the software version.
6. The display will now read “RANGE0-0” while the transducer sensors receive and send signals
from one another. The display will change depending on the distance.
7. Once the distance has been determined, the display will now be displaying the airflow readings.
Note: The auto range feature works best in non-gusty conditions. To skip auto-range, power on or reset
the unit with the program switch in the PROG position to enter the configuration menu.
