So i have a Fluke 87V, and inserted it into/between the circuit; in series (I believe that's the correct term), to measure how much a buzzer i have draws (supposed to be 50mA) - as well as just to learn/play around.
If I put the red lead into the mA slot on the Fluke 87V, the circuit doesn't work (it has a "timer" capacitor before the buzzer sounds), the capacitor doesn't charge up enough to trigger the timer (I watch it charging on another DMM). But if I put the lead into the 10A slot on the Fluke 87V, it works and measure the 50mA (well, 0.0495ish).
Can someone explain why this happens? Doesn't seem to matter where in the circuit I insert the DMM... at the neg terminal, positive for entire circuit, or just at the buzzer.
I don't believe its the fuse, as the Fluke beeps if you put the leads in wrong (set to Ohms and put red in either A or mA slot, it will beep, which I believe also tests the fuses?).
Thanks,
