Colibrick A/D Converter 3 Installation
3.3 Connection with chromatograph
Connect the cables according to one of the following diagrams in the Fig 5
on pg 7 . Use the symmetrical connection only when you are sure that the
chromatograph/detector is equipped with a symmetrical output – it is
necessary to read through the instructions for the corresponding
chromatograph.
All current
DataApex A/D Converters Colibrick , INT7 , INT9 , U-PAD , U-
PAD2 and Net-PAD use the same standard INT7 Connector.
Note: A description of the INT7 connector can be found in the chapter "Tables
and specifications" on pg 37 .

3.3.1 Connection of signal cables
Signal inputs of the A/D converters are symmetrical: + (red), - (white) and
analogue ground (copper braiding).
Caution: Shielding must be connected. It serves not only as the shielding but also as
the analogue earth against which the measurement takes place. In the
case of asymmetrical output of a detector (only two connectors) shielding
must be connected to the white lead! No lead of the signal cable may
remain unconnected.
Try to connect to the detector output of the chromatograph with the largest
possible signal level, usually indicated
as INTEGRATOR (signal
approximately 1 V). The level of the signal on the output marked
RECORDER is usually only approximately 10 mV. For easier alterations
