Do not disturb mode is preset. </p></td></tr><tr><td>D03</td><td>Bad UltraS. Signal</td><td><p>Alarm-C3</p><p>Alarm when the ultrasonic signal is poor. Do not disturb mode is preset. </p></td></tr><tr><td>D04</td><td>Off Pipe Alarm.</td><td><p>Alarm-A4</p><p>Alarm when the flowmeter is not installed correctly on the pipeline.</p><p>Preset Do Not Disturb Mode: The red light will not flash, but the flow will return to zero when the alarm occurs, and the alarm a04 will become 1. on - When the alarm occurs, the red light will flash, the flow will return to zero, and the alarm a04 will become 1. </p></td></tr><tr><td>D05</td><td><p>FlowLIM Ala</p><p>(Flow Volume Limit Alarm)</p></td><td><p>Alarm-B</p><p>Set the alarm when the instantaneous flow rate exceeds the range, which can be turned off. The default is off. </p></td></tr><tr><td>D06</td><td>Up LIM (Upper Limit)</td><td>Defines the upper normal range of flow for D04. </td></tr><tr><td>D07</td><td>Low LIM (Lower Limit)</td><td>Defines the flow normal range lower limit for D04. </td></tr><tr><td>D08</td><td><p>Hysteresis%</p><p>(Hysteresis Percentage)</p></td><td><p>Set the hysteresis percentage for the release of the flow upper and lower limit alarms</p><p>Percentages are defined as percentages of the upper and lower bounds.</p><p>The range is 0-33%, and the default value is 3%.</p><p>This parameter must be a positive value.</p></td></tr><tr><td>D09</td><td>Total Ala. (Total Alarm)</td><td><p>Alarm-B</p><p>The alarm can be set to be turned off when the accumulated flow range is exceeded. The default is off. </p></td></tr><tr><td>D10</td><td>Total Trig. (Total Alarm Trigger Condition)</td><td><p>Set the notification condition of the cumulative target value (D08), greater than the target or less than the target.</p><p>The preset is larger than the target.</p></td></tr><tr><td>D11 </td><td>Total Target</td><td>Set the cumulative target value. </td></tr><tr><td>D12</td><td>Iout Alarm</td><td><p>Alarm B</p><p>Set whether to alarm when it exceeds the range of 4-20mA, and it can be closed. The default is off. </p></td></tr><tr><td>D13 </td><td>Speed Alarm</td><td><p>Alarm B</p><p>Set whether to alarm when the absolute value of the flow velocity exceeds the range of 6m/s, which can be turned off. On by default. </p></td></tr><tr><td>D14</td><td>PulseOverlap</td><td><p>Alarm B</p><p>Pulse output (Pulse output) signal overlap alarm. The setting of parameter E03 is too large, resulting in overlapping of Pulse Output output signals. Can be turned off, default is on. </p></td></tr><tr><td>D15</td><td>IoutStatAla (Iout Status Alarm)</td><td>Set the Iout state warning mode, selectable on, off and do not disturb mode (Do not disturb), default do not disturb mode. The Do Not Disturb mode means that when an abnormality occurs, the color and LED displayed on the screen will not change, but it can still display numbers in the communication part and display abnormalities on the status page.</td></tr><tr><td>D16</td><td>Install Issue</td><td>Alarm - C2 The signal quality is not ideal due to poor installation of the flowmeter. It is recommended to lock the flowmeter evenly to achieve the best signal quality. Default non-disturbance mode: no light, Alarm C2 displays 1.</td></tr></tbody></table>
