4.7. Zero Adjustment
Description
Zero point is calibrated.
Settable range:
CLEAR : Clears the zero point calibration value to "0".
Used in case the flow cannot be stopped when calibrating the zero point.
Note 1) Where possible, stop the flow and carry out "SET ZERO" stated below.
Otherwise, an error may occur in the zero point.
SET ZERO : A point where "SET ZERO" is carried out is regarded as zero, how condition used in case the flow cannot be stopped
when calibrating the zero point.
Note 2) The flow must completely be stopped.
Otherwise, the flowing status is regarded as zero, thereby causing an error.
It takes ten seconds to several tens of seconds to complete adjustment, depending on pipe diameter.
For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.4.1.)
