Abstract: A digital adjusting signal for adjusting a multi-channel SQUID system is transmitted only to a control circuit module including a SQUID channel selected in an embodiment of the present invention and not transmitted to other modules. Accordingly, the digital adjusting signal is prevented from flowing into all SQUID adjusting channels to minimize noise generated by the digital adjusting circuit of the SQUID channel and to stably control the SQUID sensor without malfunction.
