If the pipe dimensions are not found in the database or have been altered due to deformation, the default pipe specification will be applied as the configured value.</p></td></tr><tr><td>Z03</td><td><p>Auto</p><p>Initialization</p></td><td><p>Automatically detects the ultrasonic sound velocity of the fluid under measurement to assist the flowmeter in completing the environmental parameter setup. Execute this function after <a href="../installation-and-setup/mechanical-installation">Mechanical Installation</a>, <a href="../installation-and-setup/electronic-installation">Electrical Installation</a>, and <a href="../installation-and-setup/parameter-setup">Parameter Settings</a> are complete.<br></p><p>This function begins execution only after pressing Start. Once executed, it automatically updates the A21 (Auto Initialization) setting.</p></td></tr><tr><td>Z04</td><td><p>Auto</p><p>Zero Offset</p></td><td><p>Recalibrates the flowmeter's zero point (0 flow), effectively resetting the flowmeter output to zero. During ultra-low flow measurements, setting the zero point helps correct zero-flow offset errors and improves measurement accuracy.<br></p><p>This function begins execution only after pressing Start. Once executed, it automatically updates the A22 (Auto Zero Offset) setting.</p></td></tr><tr><td>Z05</td><td>Scale Factor</td><td><p>Calibrates the flowmeter's measurement accuracy. When there is a systematic deviation between the displayed flow and the actual reference flow, the user can set a scale factor to allow the system to automatically correct the output.<br></p><p>This function multiplies the measured flow data by a fixed factor ranging from +0.001 to +1000, with a default value of +1.0. Once executed, it automatically updates the K03 (Scale Factor) setting.</p></td></tr></tbody></table>
