Name Channel’s name. This text appears as
Channel label in the chromatogram.
Units User-defined units of detector response.
Input Number of data acquisition channel.
Minimum Minimum value of the linear range of the
AD converter (in ADC conversion units).
This parameter is used to detect an under-
flow condition.
Zero A signal level on a baseline (in ADC con-
version units). This parameter is a result of
the ADC calibration.
Maximum Maximum value of the linear range of the
AD interface (in ADC conversion units). This
parameter is used to detect overflow con-
dition.
Range An input signal value in maximum in user-
defined units.

• Coef
Coefficient ADC sensitivity coefficient (weight of ADC
bit in user-defined units).
Noise Estimated baseline noise value of the
channel in ADC conversion units (bits).
Shift Shift of the current channel in time. This
parameter is useful in the case of multi-
channel chromatograms only.
(multi)Channel ratio
Spectral ratios. The option is valid for multi-
channel chromatograms only.
