A typical application of the Multiply / Divide object is power measurement. When you measure the voltage over a load and the current through it, you can calculate the power by multiplying both measurements.
Properties
To control the behavior of the Multiply / Divide I/O, several properties are available. These can be accessed through a popup menu which is shown when the I/O is right clicked in the Object Tree. The properties can also be accessed through its settings window which is shown when the I/O is double clicked in the Object Tree. To open the Object tree, click the Show object tree button.
By default, the settings window only shows the most used settings. When Advanced is ticked, the extended window with all settings is shown. See also the program settings.
Mask
The Mask determines which sources are in the nominator (default) and which sources are in the denominator. This mask contains a '*' or '/' character for every connected source. By default, the mask consists of '*'-es only and all sources are multiplied. To divide by a source, set its corresponding mask character to '/'.
Some examples of */ masks are shown in the table below:
Sources | Mask | Result |
---|---|---|
1 | / | 1 / src1 |
2 | ** | src1 * src2 |
2 | */ | src1 / src2 |
2 | /* | src2 / src1 |
2 | // | 1 / (src1 * src2) |
3 | *// | src1 / (src2 * src3) |
6 | */*//* | (src1 * src3 * src6) / (src2 * src4 * src5) |
