Touch the electrode leads together and see what the current indicates. If the current goes up to the settting value, then the problem is not the SilverTron. If it reads only 2, then use a jumper wire to connect the inside of the electrode lead connect to the outside and observe the reading. If its still just 2, then the problem is internal, and you can return it to me for repair. If the current goes up to the setting, then the problem is the leads (less likely), and I can send you new leads.
