54. ters Equation This field specifies the equation used for the channel Different channel ranges have different default equations Please refer to Channels and Sensor Connections chapter for details In order to convert a process signal to a correct measurement value an equation must be applied to the channel For example if you want to use the 0 5 VDC channel to record a battery voltage output the logger will first convert the battery voltage values to digital values and save them in the memory Later when all data are downloaded to a computer Accsense VersaLog will use equation VoltageDC to convert the digital values back to voltage values If you are recording the voltage output of a transducer or transmitter and the range of the voltage refers to another measurement unit you will need to create your own equation for this conversion For instance if your CO2 transducer outputs 0 5VDC representing 0 SOOOPPM of CO2 the custom equation you need to create looks like this public double CO2Equation double Input double output output 5000 Input 5 return output For detailed instructions on how to create a custom equation please refer to the Accsense VersaLog User s Manual available for download online Cali Low amp Cali High These two fields specify the custom calibration values that are used for measurement adjustment Accsense VersaLog Data Loggers User ss Manual Page 56 The Cali Low val
