A NexSens iSIC data logger can be configured as either a data logger or a sensor, but not as both at the same time. However, there are ways to log and simultaneously display real-time data through the use of third party software.
Solution 1. Set iChart to regularly upload data to a .csv file and then have that data picked up by third party real-time display software.
Solution 2. Set iChart to send the data to an ODBC-compliant database to be used by third party real-time display software.
Contact NexSens for further assistance implementing these solutions.
