    Signal cable USB port Power inlet 1.3 Theory of operation 1.3.1 Flow cell design The flow cell has an internal volume of 0.8 µL, and the microprocessor controls conductivity measurement. The cell constant is typically 16/cm, and you can adjust it from 13/cm through 21/cm.

  • Page 17: Autozero

    1.3.4 Autozero You can eliminate the eluent’s contribution to conductivity using the Autozero function. When you select Autozero, the detector measures the eluent conductivity and assigns it a value of zero. Thus, any sample ions appear as positive or negative measurements, relative to a zero baseline.

  • Page 18: Preparing And Operating The Detector

    Preparing and operating the detector Install the detector as described in this section. 2.1 Stacking system modules This procedure applies to system modules equipped with interlocking features. Important: For the order in which to stack modules, contact your field service engineer.

  • Page 19: Connecting The Tubing

    To stack the modules: Place the rear feet of the module that you are adding atop the previously added module in the system stack, and slide it backward until its rear alignment pin rests in the rear alignment slot on the previously added module. Figure 2–1: Aligning pins with slots Alignment pin (2) Alignment slot (2)

  • Page 28: Safety And Handling

    To prevent flow cell failure: • Do not attempt to disassemble or rebuild the flow cell. • The pressure through the 2432 Conductivity Detector flow cell must not exceed 5000 kPa (50 bar, 725 psi). Adjust flow rates accordingly. • Do not connect any tubing or device that can create backpressure exceeding the flow cell's maximum pressure rating.
  • Page 29 Note: The module contains two fuses, one you can replace using the procedure below and one you cannot access. If changing the assessable fuse does not restore power, contact Waters Technical Service. Notice: To avoid damaging system modules, before replacing an opened fuse, determine the cause of the fuse's failure.
