When using a multimeter, how far apart do you need to place your probes to get an accurate reading?

To achieve an accurate reading with a multimeter, placing the probes at least 0.25 inches apart is typically recommended for most applications, particularly when measuring voltages or resistances in electrical circuits. This distance helps ensure that the probes make sufficient contact with distinct points in the circuit, allowing the multimeter to accurately measure the voltage or resistance without interference from other conductive paths or components nearby.

Spacing the probes too closely together may cause the readings to be affected by adjacent circuit elements or electrical noise, leading to inaccurate results. In certain situations, a greater distance between the probes may be necessary depending on the specific components of the circuit. However, the 0.25-inch spacing strikes a balanced approach between maintaining accuracy and practical use in typical scenarios you might encounter as an aerospace assembly mechanic.
