Attaching chambers and extensions manifolds

One cable and tube bundle (part number 9982-056) is used for each chamber and extension manifold.

Chamber cables and tubes

Chambers attach to the LI-8250 Multiplexer and the 8250-01 Extension Manifold with the tube and cable bundle (part number 9982-056).

1. Attach the tubes and cable to the LI-8250 Multiplexer connection panel.

   For the cables, align the key with the slot and then tighten until snug. Press and turn a little more until the connector is fully seated.

   

2. Attach the tubes and the cable to the chamber.

   Be sure that tube and cable connections for each chamber and each extension manifold are made to the same port.

   • For each Long-term Soil Chamber, connect the thermistor cable to a SENSOR port on the chamber. See Long-term Soil Chambers for more details.

     

   • For each Automated Canopy Chamber, connect the motor cable to the connector labeled MOTOR. See Automated Canopy Chambers for more details.

     

   • For flasks, see Connecting tubes and thermistors to flasks.
   • For custom chambers, see Using custom chambers.
   • For a profiling system, see Atmospheric profile measurements with the LI-8250 multiplexer system.

8250-01 Extension Manifold cable and tubes

Extension manifolds connect to the multiplexer with the cable and tube bundle (part number 9982-056). The multiplexer provides power to the extension manifold and to any Long-Term Chambers connected to the extension manifold (unless you are using the flask sampling kit). The multiplexer and extension manifold use quick-connect fittings for air tubes and connectors for the cables.

1. Attach the quick-connect fittings and the cable connector to the connection panel on the LI-8250.

   Be sure that tube and cable connections for an extension manifold are made to the same port.

2. Attach the quick-connect fittings and cable to the Extension Manifold connection panel.

   For the cables, align the key with the slot and then tighten until snug. Press and turn a little more until the connector is fully seated.
