Connecting Signals to the Digital Multimeter (DMM)

    Last Modified: May 14, 2018

    The DMM on the NI ELVIS III is isolated and its terminals are the three banana jacks on the instrument panel. For DC Voltage, AC Voltage, Resistance, Diode, and Continuity Test modes, connect signals to the VΩ and COM connectors. For DC Current and AC Current modes, connect signals to the A and COM connectors. For Capacitance and Inductance modes, connect signals to the Current-Voltage (IV) Analyzer connector. The Current-Voltage (IV) Analyzer is non-isolated and its terminals are three screw terminals on the instrument panel.

    The DMM has a fuse for over-current protection. The DC Current and AC Current modes are disabled if the fuse is blown. Replace the fuse (2.5 A fuse, 5MF2.5-R) to re-enable the current modes. Refer to the connectors diagram in Using the Instruments to locate the DMM fuse.

    1. Capacitance and inductance measurements are done through the Current-Voltage (IV) Analyzer connector

    Note  

    For capacitance and inductance measurements, insert the component directly into the IV Analyzer screw terminals to achieve the highest accuracy measurements. In cases where the component cannot be directly inserted, use short wires to minimize parasitic effects that impact the overall impedance of the device under test.
