Hi Yvonne,
What this is saying is that 100% of your samples had an uncertainty greater than 1%. It would appear that the current range setting for the idle worket is set too high for the interval. Try editing the range setting for idle in the SERT GUI power analyzer options or by editing listners.xml. It should be set to the average value reported during test, or in this instance what you see on the analyzer when there is no activity on the SUT.

https://www.spec.org/power/docs/SPEC-Power_Measurement_Setup_Guide.pdfThe following is an excerpt from section 2.6:
"For compliant SPECpowerbenchmark runs, specific uncertainty requirements have to be guaranteed according to the SPECpower Run and Reporting Rules. The uncertainty of a measured power value depends on how well the configured volt and ampere ranges fit to this value. The formulas to calculate the uncertainty often directly include the configured volt and ampere ranges. Selecting the volt range is quite easy as the voltage depends only on the power source and does not change during the test. Selecting the ampere range is more complex, because it differs with the SUT’s power consumption during the benchmark run. A large difference between different load levels may even require individual ampere range settings for each level. PTDaemon has the ability to select the closest range appropriate for a requested value. The information is maintained on a per-analyzer basis. For example, if you specify a range of 2.2A and the analyzer in use has ranges of 0.5, 1.0, 2.0 and 5.0A, PTDaemon will set the analyzer to the 5.0A range."
