To set up a current shunt:
1. Connect the Instrument end of the Doble supplied Analog cable to a
pair of Analog channel banana jacks.
The Analog Channel inputs are polarity sensitive.
2. Make sure to attach the shield (green/yellow) banana plug to the
chassis ground (green/yellow) banana jack on the Event module.
Multiple shields can be stacked (see Figure 4.13 on page 4-30).
3. Taking appropriate safety precautions, use the attachment accessories
provided to attach the other end of the cable across the device to be
monitored, either directly across the device or at the terminal block.
For best results, Doble recommends that the shunt be installed on the
low or neutral side of the circuit through which the test current flows.
