Voltage and current sensor issues

Hi! I bought on your site original voltage and current sensor, and configured it as described in here:
But it doesn’t work. It shows me that voltage is 0, and after restard ArduPlane doesn’t work at all (crash during initialiaztion stage).

Well, it started to work after all. I removed /var/APM/ArduPlane.stg file, first opened APM Planner, and set up there preset. In first place. Also check, that _MULT params are non zero, otherwise you will get crashed during ArduXXXX startup.
