Good day, tumpang thread kejab

I haz got my first multimeter, it's uni-t that cost me 50 bucks, I just wanna know if my dumbass has fucked up the meter already, I buy this to do one thing only, to read the lamp current drawing off a compatible ballast.

Here is what I do, I just do what some utuber did anyway



I turn the dial to 6 o'clock, which says "10A", if I understand correctly it mean it would read up to 10A and anything above would blow the fuse after 10 seconds? I've tested several lamps that ranging from 0.37A to 3.25A operating current but all it does is 0.00 on the LCD, the lamp do fire up normally. Or maybe I connect the wrong way or something? Any inputs from otai sifus will be appreciated.

I wasn't be able to get the readings of amps draw so I gave up. Because I suspected some ballast using the wrong label to run different wattage lamps, like manufacturers trying to save cost by making one ballast for 40W fluorescent lamps, then they also put a different label on the same ballast to run 20W lamps which severely overdriving a smaller lamp, they are the same thing with different label but they don't care since it could light up both lamps but doing so will kill the lamp and overheat the ballast so much quickly.

I've tried various settings and it never went pop so I'm safe, at worst I may just trip the circuit breaker.
