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 mA.

Measure step by step

A current source keeps the current through the load constant (example: 10 mA). Connect the multimeter in series and read the current on the mA range; plug the red lead into the mA input. On the V⎓ range, the open-end voltage rises to the source's compliance limit.

At the open end the output voltage rises up to 30 V: do not touch the terminals with bare hands. Do not connect a voltage source to the mA input.
