Microamps measurement

[metceyn]

I am trying to do the project in this link (https://www.openhardware.io/view/380/Micro-nano-ampere-meter-double) but I could not understand the connection parts. If anyone has information, can you help me? My goal is to measure between 0-50 microamps.

I don't know the mentioned project, but for this type of measurement people like to use the uCurrent.
It would allow you to measure 0-50 uA. It can measure up to ~1400-1500 uA with a full 3V battery, when set to the uA range. It's output is in mV - so you'd need to hook a multimeter to its output to display the measurement.

Limitation: It's not good @ measuring pulses. So if you're not measuring a constant current but pulses of currents, like from a boost converter, things get complicated.

@canique if tou had read the description of the project, you would have noticed that it mentions uCurrent.

@mfalkvidd you're right. I've noticed it later, hadn't clicked on the link before. The project uses a uCurrent for calibration.
