| --- | --- |
| **Lower Limit** | Random value outputs will not go below this setting |
| **Upper Limit** | Random value outputs will not go above this setting |

### Example Usage as an Expression:

Random(0,1) - Returns random value s that vary between 0 and 1.

Random(-4.2,15.8) - Returns random values that vary between -4.2 and 15.8.

### Example Reference Chart:

The following example shows Random(0,1) overlaid with indicators of the high, low, and mean values. A distribution from 0 to 1 has a highest value near 1, lowest value near 0, and a mean near the middle point between the bounds, which in this case is 0.5.

The example below shows random noise being added to a tank level, and then smoothed out afterwards. This illustrates that Random can be added to signals, and fed as input to other functions.
