SEN0161 PH Meter

Last year I bought the SEN0161 ph Meter. It is a kit with an electrode and a simple PCB for measuring ph. I have never tested it until today. I uploaded the sample code (found here: http://dfrobot.com/wiki/index.php/PH_me ... SEN0161%29 ) onto the arduino and noticed that the value is exactly the same with the probe connected tho the bnc connector or not.
I tried to short-circuit the connector on the PCB and I measure two volts, so it seems working. Is my probe broken?

I will develop arduino code with this, When It will be stable, I go back on the forum to put the code !
see you later

2016-06-23 19:45:11 Typo I made in my last reply that the unit should be mV but not V, and after confirmed with our engineer, the -421mV ~ 412mV is converted to 0-4V. And the potentiometer is to slightly adjust the Gain of the amplifier, just for reference it changed original gain from 2.4 to 2.6...

2016-06-23 19:18:45 Hi,
Ok I unterstand.
Can you explain the conversion made with electronic board ?
is it simple scale conversion (-5/+5 V) to (0/5 V) ==> scale 0.5 or it's different; how the potentiometer runs ? how many turns are possible on it ?
thanks for your answers;
