The function has one parameter named Input. This value is read-only and it is the result of thecaller function or the conversion from digital value to the unit measurement for that channel type ifthere is no caller function. In the latter case, Input refers to a value within the range of 0 – 10 voltfor a 0 – 10 VDC channel type.The function must return a value, which is the result of the conversion.The above equation is illustrated below. It indicates that for the input range 0 – 10, the output isproportional to the range of 0 – 5000. For instance, A CO2 transducer has output of 0 – 10 VDCrepresenting 0 – 5000 PPM of CO2. The transducer is connected to the 0 – 10 VDC channel of thelogger. When the transducer outputs 0 Volt, the physical measurement should be 0 PPM of CO2.When the transducer outputs 10Volt, the physical measurement should be 5000 PPM of CO2. Whenyou apply the above equation to the channel you should get the correct conversion.Create EquationTo create a custom equation:Click Equation button from Main tool bar.In the equation dialog, click Create button to create a new equation:SiteView User’s Manual – Microedge Instruments Inc. 71/200
