Fluke 43B - Powering the Fluke 43 B

7
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 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 i400s 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”).
