Accuracy of component based power measuring devices forms a necessary basis for research in the area of power-efficient and power-aware computing. The accuracy of these devices must be quantified within a reasonable tolerance. This study focuses on PowerInsight, an out- of-band embedded measuring device which takes readings of power rails on compute nodes within a HPC system in realtime. We quantify how well the device performs in comparison to a digital oscilloscope as well as PowerMon2. We show that the accuracy is within a 6% deviation on measurements under reasonable load.
