The top area of the Measurement Tab is used to display the Measured and Converted (if applicable) Values for each of the K-Boxes Channels and to Assign Conversion Tables and Formulas to channels:
Click on the radio button of the channel you wish to display. The Actual Measured Value will be displayed. If a ‘Conversion Table’ or ‘Formula’ is assigned to that channel, the converted value and units will be shown along with the formula or name of the conversion table:
Using a conversion table, the K-Box can use a table to map measured values to engineering units. For example, this feature could convert the output voltage from a pressure sensor to pressure in PA, allowing sensor values to be interpreted easily.
To create a ‘Conversion Table’, follow the following steps:
Clicking the Edit button allows the conversion table to be created.
Fill the Name field, Y-Axis Units and add points to the Conversion table:
In this example, the conversion Table has been named V-PA. The units it will convert to have been set to kPA. Once that is done, the Add button adds the various points on the graph. That describes the sensor’s transfer function (in this example, 0,0; 200,442; 400,981, and so on)
Save the conversion table by pressing OK:
Use the following steps to apply a Conversion Table to a channel.
Click the Channel you want to assign the Conversion Table to:
If the Channel already has a Conversion Table or Formula assigned, the corresponding button will be highlighted in red.
If you wish to remove the existing Conversion Table or Formula, click Table or Formula and uncheck the tick by clicking on the tick next to the Table in use or the
button.
Click the name of the Table you wish to apply to the Channel.
The Conversion Table will immediately be applied. You will see the name of the conversion table in use for the selected Channel.
Use the following steps to apply a Formula to a channel:
Click the Channel you want to assign the Formula to:
If the Channel already has a Conversion Table or Formula assigned to it, the corresponding button will be highlighted in red:
If you wish to remove the existing Conversion Table or Formula, click Table or Formula and uncheck the tick by clicking on the tick next to the Table in use or the
button.
Select Formula / Edit:
Enter the Formula you would like to use, e.g. Y=0.75*X+12.3 and also the units of the output:
Click OK to apply the Formula to the Channel.
The Formula will immediately be applied, and you will see the Formula in use for the selected Channel.
