Reset DG-1000 

A recovery disk (micro-SD card) is available from BlowerDoor GmbH. It should be used only if you need 
to reset the DG-1000 to the factory settings. 

If a situation arises where the recovery disk may need to 

be used, consult with BlowerDoor GmbH technical support.

Note: 

All air flow measurements shown on the DG-1000 are adjusted to an air density standard of 
1.204 kg/m³. This corresponds to an air density under ambient conditions of 20° C and 101325 Pa. 
The adjustment is based on the CGSB regulation CAN/CG-SB-149.10-M86. This measurement does not 
include the actual airflow through the fan.
