CHAPTER 10 - WORK WITH EQUATIONSWhat is Equation<strong>Data</strong> logger records a channel input measurement in digital value, which does not represent thephysical measurement. In order to do the correct conversion Equation is introduced.Equation is a software functionality handling the conversion from one data format to another.<strong>SiteView</strong> uses equation name up to 16 characters to identify an equation. Each time when <strong>SiteView</strong>loads status of the logger it locates the equation by the equation name saved in the logger. If theequation is predefined (built-in equation), <strong>SiteView</strong> uses predefined function to convert the data. Ifthe equation is customer defined (custom equation), <strong>SiteView</strong> loads the contents of the equationfrom the equation file and does the conversion.Built-In EquationsThe following tables contain all built-in equations:Equations for Temperature ChannelsChannel Type Equation Name Equation DescriptionInternal ThermistorTemperatureTemperatureResistanceResistanceExternal ThermistorTemperatureTemperatureResistanceResistanceTemperature Temperature TemperatureThermocoupleThermocoupleB Thermocouple EquationsThermocoupleEThermocoupleJThermocoupleKThermocoupleNThermocoupleRThermocoupleSThermocoupleTVoltageDCVoltage DCEquations for Relative Humidity ChannelChannel Type Equation Name Equation DescriptionRelative Humidity RelativeHumidity Relative Humidity<strong>SiteView</strong> User’s <strong>Manual</strong> – Microedge Instruments Inc. 69/200
