Rosemount Raptor<br />

10. Specify parameter value range to be used in various windows for<br />

presentation of measurement data. Also choose whether to use<br />

measurement values (Automatic) from the available instruments or<br />

<strong>manual</strong> values.<br />

The Free Water Level, Liquid Pressure, and Vapor Pressure parameters<br />

are set to Value Source=Manual by default. Therefore, the tank needs to be<br />

configured for automatic measurements when these type of instruments are<br />

used.<br />

The Value Entry window allows you to disable automatic measurements for<br />

selected parameters in case you need to remove an instrument for service<br />

purposes.<br />

To use <strong>manual</strong> values do the following:<br />

1. Chose a measurement variable in the left-hand list of the Value Entry<br />

window.<br />

2. Set Value Source to Manual.<br />

3. Type the desired value in the Value entry field.<br />

Now the automatic measurement is disabled for the selected tank<br />

measurement variable. Manual values are marked yellow in order to<br />

distinguish from automatically measured values.<br />
