Question: 1 / 400

When using an inductive current probe adapter on a DMM, what adjustment must be made?

The probe must be set to maximum voltage

The thumb wheel on the probe is adjusted to zero on the DMM

When using an inductive current probe adapter with a digital multimeter (DMM), it is crucial to ensure that the measurement readings are accurate. Adjusting the thumb wheel on the probe to zero on the DMM establishes a reference point, allowing the user to account for any background or offset currents that may affect measurements. This step is essential for obtaining precise measurements of the current flowing through a conductor, as it eliminates potential inaccuracies due to noise or stray currents.

This adjustment involves ensuring that the DMM shows a reading of zero when no current is being measured. By setting the probe to zero, users can accurately measure only the actual current flowing through the circuit, as opposed to including extraneous readings that may otherwise skew the data. Proper setup is vital for effective diagnostic work in automotive electrical systems.
