110 - AMPLIFIER BASELINE OFFSET ADJUSTMENT

Offset refers to the zero point or baseline of a signal. BIOPAC biopotential amplifiers (including the DA100) are preset at the factor to Offset 0.

When recording in AC mode, the signal should be centered on 0.
When recording in DC mode, the offset of the amplifier will vary with each transducer.
