Recorder and Computer/Integrator Connections
The recorder and computer analog output connectors are located on the right panel. (See
Figure 2-3 on the next page.) Cables are supplied with the Series 200 UV/VIS LC Detector
for both connectors. The REC connector has a 10 mV/FS analog signal output and should be
connected with a chart recorder with the same range for optimal performance.
Most integrators/data systems have a 1 V/FS input. If the COMP output is set to 1 V/AU,
the data system will have a calibration of 1 AUFS. If small (< 1 AU) peaks are to be
observed, this gives maximum sensitivity. Large peaks, however, will be off scale since the
instrument has a dynamic range of 3 AU. In this case, it is necessary to select the 0.5 V/AU
or 0.2 V/AU level for the COMP output. Similar comparisons can be made for data systems
having input levels other than 1 V/FS Select the output level which gives the best signal
range, taking into consideration the data system input characteristics and the largest antic-
ipated peak.
Both the REC and COMP outputs may be
used simultaneously.
