Answer: The sigma-5DF is supplied with a standard Dual Field cable with Binder connector, type CCBL-LBD-3.0M. With this cable it is possible to connect all the CD Leycom combined Pressure-Volume catheters and the Numed conductance-only catheters (when supplied by CD Leycom). For the Millar combined Pressure-Volume catheters you will need a special cable, type CCBL-LRD-3.0M (Dual Field), to connect the volume-arm of the catheter. For the pressure-arm of a Millar catheter you will need a separate connection-set, to be purchased from Millar. You will find several different cables to connect 8, 10 and 12 electrode catheters in SF or DF excitation in our accessories product-list.
