Ah, you both are right about the multimeter's inaccuracy at the nanoAmp level. But the thing is, the measurement is not even in the nano range yet, and barely into the micro range. I'm currently measuring it on mA notch, reading 00.38mA and when switched to µA, it reads 380.0 µA. Also tested it using a suckier multimeter with the same result.
Between sketch C and D, I'm reading 0.40 mA (400 µAmps). With ADC off, it reads 0.38mA (380 µAmps). I have burn the fuse and set to 8 MHz, yet the power consumption is still at 0.38mA:
- low_fuses = 0xE2
- high_fuses = 0xDF
- extended_fuses = 0x07
