Operation
Caution
Excessive internal heat will destroy the SFAM.
Avoid high cycle rates with large pressure amplitudes. Otherwise, the admissible
limiting temperatures of the used materials will be exceeded.
The air mass flow displayed by the SFAM refers to the standard conditions that were set under
“Options” in the special menu.
When comparing volumetric flow rates:
Make sure that the volumetric flow rates to be compared (e.g. operating volume flow rate, amount
supplied by a compressor, measured values of a flow sensor from another manufacturer) refer to
the same initial conditions.
After the supply voltage is switched on, the SFAM needs a warm-up time of 5 minutes until it
achieves the specified accuracy.
Reset SFAM to factory setting
(even if the security code cannot be found)
Note
By resetting to factory settings, the current settings are lost. If required, make a note of
these settings before resetting.
To reset the SFAM to the factory setting, proceed as follows:
1. Switch off the operating voltage.
2. Press and hold all three setting elements (A push B push the Edit button) at the
same time.
3. Switch the operating voltage off and then on again.
The SFAM is in RUN mode.

Maintenance and care
Switch off the following energy sources before cleaning the exterior of the device:
–
Operating voltage
–
Compressed air.
If necessary, clean the SFAM from the outside.
Soap suds (max. +60 °C), petroleum ether and all non-abrasive cleaning agents may be used.
