- Transfer
Characteristic:
±1500 mV input gives ±3000 mV Output(1:2 transfer)
- Isolation:
•4
High-quality Electrode Amplifier Channels with complete Isolation.
•Each
Channel has its own Ground (GND) which is not connected to the GNDs
of the other Channels. Thus, Electrical "Ground Loops" are
avoided as the 4 channels are "Galvanically Isolated" from
each other.
•The
Input Ground of each channel is connected to the Output Ground of
each channel, when using a Data Acquisition System, use it in "Differential
Input" or "Isolated Inputs" Mode to get the best results
in respect of interference and signal noise
