Inputs
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 43 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 (
).
Use this input only 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”).
