2.5.3 Model 1327 Chart Recorder
When used with the BioLogic LP, the Model 1327 Chart Recorder automatically starts when a method
begins and stops when the method ends. The BioLogic LP’s Manual mode operation of the chart recorder
may be used to start and stop the chart recorder.
The following cables are required to connect the Model 1327 Chart Recorder to the BioLogic LP Controller:
• System Cable 2: Through this cable, the BioLogic LP outputs the UV analog data signal, pen
up/down, and Stop/Start commands to the Model 1327 chart recorder. It connects to the BioLogic
LP’s UV Chart port and to the chart recorder’s DIN connector.
• System Cable 4: Through this cable, the Conductivity analog data signal is sent from the BioLogic
LP to the Model 1327 Chart Recorder. The cable connects to the BioLogic LP’s Cond Chart port
and to the chart recorder’s channel 2 banana plug connectors.
• Power cable and adapter: Operating power for the Model 1327 Chart Recorder is supplied via the
jack next to the chart recorder’s DIN connector. (Note: The Model 1327 Chart Recorder may also
be run on batteries.)

In addition, following chart recorder controls should be set:
• All chart recorder controls with a green setting should be set to their green setting.
• Paper speed dial: Select a chart speed appropriate for the separation being performed.
• Manual paper feed: Using this switch, select Paper “fast feed” to quickly advance the paper to the
desired position.
• Baseline adjustment dial: These dials allow for pen position adjustment. The “zero” position of each
pen is adjusted using the thumbwheel for each channel. When adjusting the pen’s zero position,
make sure that the BioLogic LP instrument (UV or Conductivity Monitor) is zeroed first.
Note: The chart speed is set at the recorder itself. The BioLogic LP Controller does not control this
function.
This instrument is described in detail in its separate documentation.
