Instruments in AseptSoft are the components representing Sensors, timers, and all the parts from the process that have an output.

They can measure a lot of things, like the Temperature, Time, Pressure, etc.

They can be used in the Algorithm Design in formulas.
Example: If you want to do something when a pressure level is reached, then you can create the formula (using the Formula Manager, see the tutorial about it) as: “PIT PI = Parameter Preparation Pressure Level“. (See the related tutorials about Parameters as well.)

When an Instrument is in use in the active algorithm step (his text is mentioned in the Condition field) you will see it highlighetd in the PID.
