2.9.8 Model 1327 Chart Recorder
The Model 1327 chart recorder is a dual-pen chart recorder that is compatible with many detection devices.
The chart recorder includes the following features:
• Two-channel, dual-pen capability.
• Compact in size (31 x 23 x 7.6 cm).
• Voltage ranges from 1 mV to 20V.
• Twelve chart speeds for recording methods.

The DuoFlow Controller outputs the UV analog data signal, pen up/down, and Stop/Start commands to the
Model 1327 chart recorder via the Workstation’s UV Chart connector (cabled to the chart recorder using
System Cable 2 mini DIN to standard DIN). The Conductivity analog data signal is sent from the
Workstation’s Conductivity Chart (Cond Chart) connector to channel 2 of the chart recorder using System
Cable 4 (mini-DIN to banana plugs). The chart recorder should be set to all green settings (1V). The chart
recorder is described in detail in its separate documentation.
Note: The chart speed is set at the recorder. The BioLogic DuoFlow does not control this function.
Event marks are recorded on the chart recorder for the following:
• Fraction Collector Advance: When the fraction collector advances to the next tube.
• A manual event mark from the Run screen. Pressing the Event Mark button on the Run screen
allows you to “mark” events as they happen.
Non-Bio-Rad UV detectors: If the Model 1327 chart recorder is used in conjunction with a SIM and a third-
party detector to replace the DuoFlow UV Detector, System Cable 20 should be used to control the
recorder. Channel 1 signals should be sent directly from the third-party detector using a bare wires-to-
banana plug cable. In this case, the appropriate input voltage range must be selected on the recorder. Refer
to the documentation for your non-Bio-Rad UV detector.
2.9.9 Generic Chart Recorders
A non-Bio-Rad chart recorder may be used as an integral part of the DuoFlow system. If the DuoFlow
system’s UV detector is used, a mini-DIN to breakout cable (System Cable 7) must connect the
Workstation’s UV Chart connector to the chart recorder. Pen Up/Down and Start/Stop functions are available
providing the control polarity of the generic recorder is compatible. See the pin-out information in your chart
recorder manual.
Conductivity signals require a Bio-Rad mini-DIN to banana plug cable (System Cable 4).
Set the chart recorder’s input signal voltage to 1 V for both BioLogic DuoFlow UV detector and Conductivity
monitor signals. Chart speed is set at the recorder itself, it is not controlled by the DuoFlow system.
