Figure 4. Measurement Connections

INPUT 1: Use the red test lead on input 1 ( ).

COM : Use the black test lead on the COM input ( COM).

Use these inputs for all voltage measurements, and for Ohm, continuity, diode capacitance and temperature measurements.

The Fluke 43B common inputs (red INPUT 1 shield, gray INPUT 2 shield, and black COM input) are connected internally via self-recovering fault protection.

INPUT 2: Use the 80i-500s AC current probe on input 2 ( ).

This input is mainly used for current measurements. Use the BB120 banana- to-BNC adapter to connect the current probe.

Note

If you use other test leads or probes, change the probe settings in the instrument setup menu (see “Selecting Probes”).
