The baseline signal from the SCD and NCD can be adjusted from 0 to ±1% of the full scale recorder output using the offset control. (e.g., +10 mV to -10 mV for a 1 V full scale setting). This control can be used to offset the background signal.

Dual Plasma Controller Controls

The Agilent Dual Plasma Controller provides easy access to basic settings.
