Hello.

Has anybody dealed with AEM thermocouple amplifier?
I am trying to connect 4-channel amplifier(30-2204) to the EMS. Everything is straight clear excepting one wire: grey(SIGNAL GND). Description in the manual is quite vague, "used if a differential input is required". Could one explain how should I connect this wire and in what cases it's required?
