What should the noise level be, and what are some of the best ways to minimize noise?
The noise level of the MED64 system is very low because of its low-impedance electrodes (7-10 k ohm at 1 kHz typically.) Noise levels differ from setup to setup, but the level usually should be several micro volts at the time scale of 20 ms/division. The main ground should be simple by connecting the MED amplifier and peripheral items such as perfusion cap, peristaltic pump, and temperature controller in a single line. Please don’t make a “ground loop”. Also, the level of the solution must be high enough to cover all four reference electrodes. Please refer to the MED64 System Handbook Vol.1 to help minimize noise.
