SiteView uses .Net C# language as the script. The script or the source code is in theformat of function call.A function specifies the name of the function, the types and number of parameters it expects toreceive, and its return type. The body of the function implements the conversion from one unitmeasurement to another. A simple custom equation looks like this:public double CO2Equation(double Input){}double output;output = (5000 / 10 ) * Input ;return output;The above equation has the name “CO2Equation”. The name must be unique and with maximum of16 characters.SiteView User’s Manual – Microedge Instruments Inc. 70/200
