5.1.2.2
Setup and uploading of VMT (Linearization curve – VMT)
This function is required to prepare a conversation chart between level and volume, with max. 20 points. Each provided value must be higher than the previous one.
Units of length and volume might be altered without the necessity to modify the data (Length unit, Volume unit) in the chart.
The 2 units of measurement on the left and right sides of the chart inherit the unit settings of length and volume. This rule should be kept in mind when filling the
corresponding chart (Length unit and Volume Unit).
Important: The volumetric measurement is exclusively possible after the conversional chart is prepared.
To fill and set up the level/volume chart of the device, the “device programming window/Linearization curve” tab is to be selected in EView2.
Please fill or modify the chart here, similarly to what is written in chapter 6.4 of the user manual of EView2.
One difference to the process described in chapter 6.4 is that the turning on/off function cannot be selected from the „Linearization” drop-down menu for this type of
device, because this function is regulated by the „Current generator mode” parameter. The VM chart is activated if this parameter (Current generator mode) is provided
as „Volume” or „Ullage Volume”.
The other difference is that there is no “VMT” tab in the programming window (Advanced mode), only a „Linearization curve” tab in „Basic” mode.
In case if the required modifications completed in the chart, or if the chart is properly filled, then please select “Send” button (which is located to the right side of the
window under “Get”) on the “Linearization curve” tab, to download the chart to the device.
5.1.2.3
The “Device status” window and the „Markers” diagram
To open the “device status” window in EView2, please select the desired device from the “device list” drop down menu of the main window by a right-click, and select
„Show device status window” from the pop-up menu (please see: chapter 6.3 from the EView2 user manual)
The „Markers diagram” is – similarly to device status – opened by selecting “Markers” from the pop-up menu. The opening window enables monitoring the status
changes of the device, visualizing it by a graph. Each status bits have its own line in the graph, with a “0” or a “1” value is presented. Status “1” stands for the status is
active, with “0” indicates inactivity.
