hello!
Im trying to find how much current is going to a viewfinder i have:
I detached the viewfinder from the bulk of the camera and then i found the + and - wires going to the viewfinder. then i measured different values from + to - using a multimeter:
direct voltage= 5.12 V
alternating voltage= 10.4 V
so that was good i think, then i measured the resistance and i got a bunch of different values (can someone please explain this):
Ω at - 200 = -61 on multimeter
Ω at - 2 K = -1.583 on multimeter
Ω at - 20 K = -7.05 on multimeter
Ω at - 200 K = -191.7 on multimeter
Ω at - 2M = -0.601 on multimeter
note* the values showed negative because when i measured with the red multimeter tester touching the + source of power (from the bulk of the camera/camera battery) it did not work for some reason. so as an alternative i measured with the red tester touching the - source of power from the camera battery
Now about the current measuring, i have the bulk of my camera powered on and the view finder attached, the view finder is on and working because i can seethe blue screen, but as soon as i try to measure current the entire camera powers and the current falls to 0 quickly. my camera makes a weird sound when i do this
CAN SOMEBODY PLEASE HELP ME MEASURE ALL THESE VALUES?!
the reason i need to do this is because i want to power the viewfinder using a smaller battery source like 4 aa's, so i need to match up all the values so i dont fry my expensive viewfinder
THANKS !!!!!!!!!!
