dragon osd current sensor problem


I've finally just received my new 100Amps current sensor from IF for my dragon osd. Before I used a 50Amps current sensor from NGHobbies. Before with the 50Amps current sensor the lowest current draw has been not less than 0.2Amps. Now using the 100Amps sensor, current draw is 0Amps.
Is the sensor broken or is there another problem with the new 100Amps sensor I'm not aware of?
I hope there is some1 who can help me.
Thanks a lot!

Hi Don,

Two things come to mind immediately - first of all, did you change the IMULT setting in the menu to accomodate the new sensor. If not, you should do that.

Assuming that you did, you should know that the 100A sensor is less than half as sensitive as the 50A sensor, so you will get less resolution with it than you did with the 50A. This is one of the reasons why I prefer the 50A unless I am really drawing that much current as to need the 100A.

Hi Daniel,
thanks for your answer.
No I didn't change settings yet. Ih hope this will solve the problem.

Now you say, the 50Amps sensor is more precise; is it possible to run it even my max current is up to 80Amps?
Thnaks a lot
