Hi all,
just bought a Q450 v3 quad frame.
I solder all ESCs to the Q450 v3 power board.
To check if everything is ok, I used my multimeter in transistor mode and:
- 1st, + with +
Result: Started with a value that reached 0 after a few seconds (common behavior when connectivity exists)
- 2nd, + with -
Expecting: No value
Result: Value on screen will rise until I get a stable 1550
At this time I though I had a short circuit
So, I turned the multimeter to the resistance mode and repeated the tests:
- 1st, + with +, R = 0
- 2nd, + with -, R will increase (didn't wait for the final value)
I had a few extra ESC around and tried to connect the multimeter to their battery terminals and I got similar values (if I connect the multimeter to the battery connector I get value in the transistor mode and in the resistance mode like in the board after soldering the ESCs).
Does this mean that this is the normal behavior? Or I have a short circuit?
BTW: I run the tests before soldering the ESC and the transistor test returned a negative conductivity
Thanks for all your help,
Luis Pinho
