I’m currently looking into using the OTII to measure energy use over longer term time periods… here’s what we’re currently thinking:
Using a headless linux setup on a x86 machine with the OTII attached to a standard DC bench supply.
OTII with premium license to both source and sink current (if charging)
Timescales would include tests for up to one week.
When we have run a cycle of tests, if there are anomalies in the power consumption we would like to be able to pull off the logs and examine them. This could be in a native format, or as a CSV file - we don’t actually care. I guess it would be useful to be able to open the native format so we can examine with the OTII software on another machine.
My questions are:
1/ Does the above sound reasonable - do you have any things to watch out for, or suggestions on how best to achieve this.
2/ Data logging - what would the data requirements be? Has it ever been tested over this length of time?
3/ Hardware requirements for running the linux client over a week long period? (RAM / storage / CPU)
Thank you in advance
