Connecting Clarity to chromatograph

2.3.1

Connecting 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) the 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 approx. 1V). The level of the signal on

the output marked RECORDER is usually only

approx. 10mV.
For easier alterations of the wiring, we supply a

SV8 Terminal board with screw contacts for

INT7, INT9, U-PAD, U-PAD2 and Net-PAD

A/D converters.

Note:

This SV8 Terminal Board is not suitable for

applications with small signals or with high

electromagnetic interference. This is because the SV8

Terminal Board uses leads and screw contacts that

are not shielded.
