KlimaI performed an additional set of measurements for the second prototype using a different voltmeter: Solartron 7150+.
Below you can find results and the graphs with new measurements added. The new measurements seem to confirm the previous measurement results.
Ambient temperature during measurements: 23°C
Supply voltage: 9.99V
Voltmeter used: Solartron 7150+
