I have a circuit where I have to measure tens of uA of currents.
When measuring it with a 50Eur multimeter, the multimeter shows the currents with acceptable accuracy and so far no significant influence the was observed doe to the resistance of the multimeter.
When trying to achieve the same with a 12bit oscilloscope, I have to use 500Ohm shunts to get a measurable voltage. This resistance has to much of an influence on the whole measurement.
How is it that a 6 times cheaper device (the multimeter) is so much better in measuring low values than the oscilloscope?
