Possible messages
Message
Reason
Actions
Deviations too high
Airflow sample is unstable.
Follow the instructions to repeat
the sample or quit the
calibration.
Increase higher airflow
sample
Second sample value is too
close to the first sample value.
Close the sash slightly and repeat
the higher sample. The minimum
difference between the samples
that the controller will accept is
0.3 m/sec (60 fpm).
Sensor diff too low
The monitor does not detect
any difference in the sensor
output between the 2 airflow
samples.
Check that the sensor hose is
connected and repeat the
calibration.

Calibration notes
•
Make sure the sensor hose is connected correctly at the side wall and rear of the sensor.
•
Make sure the extraction fan is running and the fume cupboard is balanced before
calibrating the monitor.
