Solution
The Chart Recorder in the NHR 9300 PowerPanel software has the capability to record the last 18 hours of data, so there is no way to use this tool to record for longer periods of time.
If you need to record data for longer than 18 hours, we recommend using a remote PC to control and log data by developing an external application. The NHR 9300 software installer includes examples for creating programs in LabVIEW, Python, C#, and VisualBasic.
These examples can be found at the following file path after installing the NHR 9300 software:
