If you have the option, rerun using a CDN, or EM Clamp. The main difference is that the BCI clamp will not damp cable resonance's like the CDN and EM Clamp will... Because setup greatly influences cable resonance's, you will find poor repeatability too. 3 volts is reasonably easy to achieve, but without specific details on your interface, power inputs, if the system is mainly Analogue or Digital, it's tough to help, Any info you are prepared to share?
