INT9 A/D converter

4 Using the INT9 card

4.2 Method Setup

Parameters of the

Method Setup - Acquisition

and

Method Setup -

Measurement

dialogs depend on the type of analysis (measurement

conditions), so they can be specific for various types of analysis. This is
the reason for them to be a part of the method.

Caution:

The parameters can't be changed during analysis.

4.2.1 Method Setup - Acquisition

Fig 13: Method Setup - Acquisition (INT9)

Select Detector

Selects the detector whose parameters will be set. If there is only one
detector (channel) configured on the

Clarity

Instrument, this control will

not be accessible.

Range

Selects the input voltage range (in mV). The selected range corresponds
to the maximum output voltage of the detector that the A/D converter can
still process.
Available ranges for
