9. Optional - if the current (4.000 to 20.000 mA) measurement features are to be used, connect the

provided Transducer Test Cable (PN 55092) to the Transducer Test Jacks (14).

When connected, this cable provides +28 VDC excitation. The internal impedance (load) is 10 ohms. The display
scaling for these current measurements are as follows:

The test cable connector wiring is as follows:

NOTE: Connector pin designations are for reference only, and are no longer a connector on newer units. See Figure 2-1
