INT7 A/D Converter

4 Using the INT7 Card

4 Using the INT7 Card

There are generally two places for setting the parameters of the

INT7 A/D

Converter

in

Clarity

:

The

DataApex INT7 Setup

dialog for setting the parameters that are set

with respect to the type of connected signal.
The

Method Setup - Acquisition

tab for setting the parameters related to

the type of analysis.

4.1 DataApex INT7 Setup

The

DataApex INT7 Setup

dialog sets the parameters of the

INT7

converter and since it depends on the type of connected detector, it is not
going to be changed often.

Fig 9: DataApex INT7 Setup

Number of Channels

Indicates the number of data acquisition channels.
