What to do if the Festo Accessories measured value is displayed flashing (with air consumption measurement)?
If the measured value is flashing during air consumption measurement with Festo Accessories, it indicates that the measuring range end value has been exceeded at least once. As a result, the specified accuracy cannot be guaranteed. To resolve this, ensure that the measuring range end value is not exceeded.
Why is my Festo Accessories measurement display incorrect?
An incorrect measurement display on your Festo Accessories may be due to: - The SFAM being operated with a non-permitted medium. To fix this, only operate the SFAM with permitted media. - The SFAM being contaminated. If this is the case, replace the device.
