Mode</td><td>Select the correction scheme, currently only the simple mode. </td></tr><tr><td>K03</td><td>Scale Factor</td><td>Fine-tune flow proportionally, default 1.0. This parameter is synchronized with Z05.</td></tr><tr><td>K04</td><td>Manual Offset</td><td><p>Subtract the fixed instantaneous flow rate from the input value, and the unit is the same as the system setting value. For example, inputting 1.0 means that when the original instantaneous flow is 3.0, the instantaneous flow will be output at 2.0.</p><p>The default value is 0.0. This parameter works independently of Zero Offset. </p></td></tr><tr><td>K05</td><td>Totalizer Scale</td><td>Adjusts the totalizer accumulation rate without changing instantaneous flow values. K05 scales the amount added to the totalizer each cycle, allowing the totalized value to be increased or decreased. Default: 1.0.</td></tr></tbody></table>
