Under certain conditions, it may not be possible to adjust the zero point:
– If the medium is in motion. Shut-off valves not tightly closed.
– If there are gaseous inclusions in the primary head. Flush the primary head and repeat the
calibration.
– If resonant oscillations of the piping are interfering with the primary head. Check the
clamping of the instrument.
– If there are active warning(s) in the status message list. (See section 4.6)
In such cases, the zero point adjustment procedure is automatically aborted and the following
message is displayed for a short time:
ZERO.ERROR
Then the converter returns to the start of the function 1.1.1:
Fct. 1.1.1 ZERO SET
Further information on zero point adjustment is given in Section 5.
The CORIMASS MFM 4085 is ready to operate after zero has been adjusted.
All parameters have been factory-set in keeping with the data specified in your order. Detailed
information for further setting of the signal converter will be found in Part B of the operating
instructions.
