That is how small quantities of heat are measured. Careful attention to experimental design, actively looking for procedures which could introduce error, performing calibration runs to observe any such errors and either reduce them to zero or identify them so that corrections may be applied to the experimental values. I would venture that the CERN people are familiar with all of this, my doubts are that the people peddling these devices are not so scrupulous.

That could explain why all of cold fusion's excess heat anomalies remain unexplained and inconsistent after all these years. They are measurement errors.

I believe there was a team that reported just last month at a LENR conference that they found that a meter they were using didn’t produce accurate results for the “spikey” data they had, and when they switched to an accurate measuring device (oscilloscope) their “excess power” readings disappeared.
