Measurement using the oscilloscope:
Measure across the resistor the voltage value. To make the measurement with an
oscilloscope, you need:
set the time base [SEC/DIV] and Volt time scale [VOLTS/DIV] of the oscilloscope in an
appropriate manner, so that the waveform of the measured voltage fills the screen of the
oscilloscope, as shown in fig.22 (the order of magnitude of exposure time to perform the
current measurement is of a few hundred ms)
fig. 22
By setting the timer on 7 mA, if the measurement is performed correctly it is expected to see
an average value of about 7 V (to each V corresponds 1 mA). As if 4 mA are set on timer
the average value that is expected to read is about 4 V.
