So basically i’m trying to read the current in my device setup connection, and as such, i have use a digital multi-meter, turn the knob to 10A with red probe to the 10A port of the multimeter and black probe to the com port of the multimeter, and lastly, i have place both red and black probes in series with my device setup. Images of rough drawn schematic as well as image of my setup is attached as shown.
With that said, the readings from the multimeter has shown an approximate value of 0.04, which i guess is 0.04 A? so the question is why is the readings wrong? As seen from the attached image,my pololu step down regulator 5V 2.5A is attached to the device setup. So why isnt the value in the Multimeter show a value of 2.5A? Could it be due to the fuse blown? if not what is the reason?
The checking of current is learned through this youtube video Measuring Current with a Digital Multimeter - YouTube
i cannot unscrew my multimeter because the screw is stuck inside. so instead i use the method indicated by this website to check my fuse. https://www.allaboutcircuits.com/textbook/direct-current/chpt-3/safe-meter-usage/
coding and setup is done according to various setup tutorials, device is working fine as intended through coding
