Sensitivity is a parameter used to generate the Waters 410-compatible
Integrator Output signal. The user interface provides a means for setting
Sensitivity as well as displaying it.
When you select this output type, the front panel displays % Full Scale as the
measured parameter.
• Filter type - Selected via front panel, timed event, and remote interface. The
Filter type is set to RC in emulate 410 mode.
• Time constant - Set via front panel, timed event, and remote interface. For the
RC filter, the settable range is 0.1 to 10.0 seconds, in 0.1-second increments.
• Voltage offset - This parameter setting, expressed in mV, shifts the
chromatogram charted from the analog output in a positive or negative
direction. Doing so voids any offsets between the detector and a data system.
The offset is added after any polarity has been applied to the output (default is
0 mV).
Voltage offset range is 0 to 2000 mV.
• Autozero on inject - The Autozero On Inject Enable enables an autozero event
when an inject start input event is received. This parameter will be set either
from the front panel or remote interface.
• Autozero delay - This delay will only be invoked on autozeros requested from an
event input or remote interface, not from the front panel. The range is 0 to 30
seconds (default is 10 seconds).
5.3.3 Setting up a run in 410 mode
After you press HOME to return to the home screen and select a Detector Output
mode (see “Configuring the detector” on page 84), you are ready to set the detector
