Hi duak,
Setting the supply to 500mV, would be good enough for the test? Anyway, what it is to be expected? I'll test this as soon as I can, and post the results.
Meanwhile, here are some more photos of the tests done so far. Voltage was set to 1, 2, 4, 8 and 16V. Precise as usual. I'm surprised!
Kind regards, Samuel Lourenço
