The FC01-CA comprises four specific measured-values memories.
They store the lowest and highest value of flow rate and medium temperature.
After switch-on or NOT-BUSY indication, the minimum and maximum values are deleted and will
be continuously updated (non-return pointer principle).
The peak values may be retrieved in the main menu and are deleted by simultaneously pressing

4 .2 .1 .3 Low flow suppression
(menu option:
ZERO SUPP .
)
The setting range for the low flow suppression option is between 1 and 10 % of the measuring
range final value. This means that flow volumes measured below that limit value are set at zero.
Selecting zero setting causes the current flow to be set at zero.
MIN. FLOW = xx%
4 .2 .1 .4 Last error (menu option: LAST ERROR)
The last main menu option to be called is the error memory.
This error memory comprises the number of the last error (see section 8). It may be very helpful
when commissioning the FC01-CA.
Other than the peak value memories described above, the contents of this memory will be retained
even upon power failure.
The user may purposely delete the error memory in the condition selected by simultaneously
