When measuring voltage with a multimeter, what should one avoid doing?

Set on the highest ohm scale
Use two probes
Check for continuity first
Calibrate the meter

The correct answer is: Set on the highest ohm scale

When measuring voltage with a multimeter, setting the meter on the highest ohm scale should be avoided because this setting is designed for measuring resistance and not voltage. When you inadvertently select the ohm setting instead of the voltage setting, the multimeter may not function properly for that measurement, leading to inaccurate or no readings at all. To measure voltage correctly, the multimeter must be in the appropriate voltage measurement mode. This allows the device to accurately measure the electrical potential difference between two points in a circuit. In contrast, using two probes is essential for voltage measurements, checking for continuity is a good practice in certain scenarios, and calibrating the meter ensures accuracy overall. Therefore, using the correct setting for voltage is crucial to obtaining reliable measurement results.
