Hold the probe and drag it to the tip of a leg. Tapping works too: first pick the probe, then the leg.

Set the range to DC voltage.

Measure step by step

4 × AA holder in series gives the sum of 4 batteries (about 6.4 V for fresh alkaline cells). Measure V⎓ at the red and black wire ends of the holder: red probe on the red wire. A measurement under load tests the batteries as well as the springs and the wires.

Do not measure the battery terminals on the Ω or continuity range, and do not short-circuit them with a metal object.
