1 V) of the 819 IC Detector (see Fig. 3) is
used for connecting a recording channel to 830 IC Interface or 771 IC
Compact Interface or from an external recorder or integration system.
The connection from 830 IC Interface and 771 IC Compact Interface is
described in Section 2.3. The polarity of the output signal at the analog
output connectors can be changed at any time under
