C
Common (Ground) Plug the patient ground electrode into either green jack on the amplifier.
Both connections are at ground connection.

deflection on the Nicolet EDX display. Use the black input jack as the
’
active ’ electrode.
E DIN Electrode Connector The DIN electrode connectors accommodate patient electrodes supplied
with DIN jacks, such as concentric needle electrodes. The DIN connectors
provide a negative-up convention.
F
Reference (+) Electrode Patient recording electrodes connect to the red (+) and black (-) pin jacks.
Negative voltages applied to the black input jack produce an upward
deflection on the Nicolet EDX display. Use the red input jack as the
inactive or reference electrode for a negative-up convention.
