I have a cheap multimeter called "Branford" and I would like to measure the current used to charge a phone. As a power supply, I use a DC generator, which I rotate by hand. Then I have a DC/DC Step Down Converter to get constant 5.2V. Then I use the power to charge the phone. It works perfectly fine and the phone is charging as it should.
However, I would like to see how much current goes through, but I get very small values. I think I'm doing something wrong, because I'm a noob in this field, therefore I would like to ask if what I am doing is correct. The multimeter front panel looks like this:
and the connections are like in the picture below. I've been looking around the internet and it looks okay, but considering that the multimeter is not the same, I would expect that there might be some other set-ups.
As you can see, I get that 0.7 (A?) which stays constant and that is where the suspicion starts. I also tried to turn the knob to the "20A" option, but there is no change. The generator has the following specs:
- Output voltage: 5V-24V
- Max load voltage: 40V
- Max output current: 1500mA
- Max load power: 20W
So, can anyone help me to figure out if it is the measurements that I'm doing wrong or the generator can't deliver more?
