Is it possible to use a shunt monitor to measure current for low values(10 mA-100mA) and if is it possible, should I use low resistive values like in most of the power circuit applications? I know that I need low resistance because it shouldn't effect my load(I don't know the value of it but probably in the order of magnitude of M(\$ 10^6 \$)Ω) but from this pdf I learned that for my application I need a resistive value of 2kΩ(200V/100mA[estimated]). I am starting to getting confused because there are also other parameters like tolerance, temperature coefficient and type(wirewound, metal, smd etc.) and I do not know which one should I take into account.
I am sorry if I can not point the question clearly, but I am a bit lost!
Edit: I just noticed that I didn't tell about the application itself. It will be an I-V tracer for samples of SiO2 wafers etc. that can log current data(using the above configuration with an instrumentation amplifier) and voltage data with a daq.
Edit2: Also as Neutronned suggest I also add the pieces of information that can be needed:
Voltage range is 0-200V and the input impadance of the sourcemeter is bigger than 10GΩ as datasheet suggests.
