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. When 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. Used for calibrating the zero point
upon stopping the flow.
Note: 2. The flow must completely be stopped. Otherwise, the flowing status is regarded as zero,
thereby causing an error.
For actual keying, refer to the typical operation indicated below. Set the parameter protection to OFF beforehand
(Section 4.4.1).
Typical operation Completely fill the piping, close the upstream and downstream valves, and proceed to zero point
calibration.
