What setting should a VOM be on to measure DC Amperage?

To measure DC amperage accurately, a VOM (Volt-Ohm Meter) should be set to either milliamperes (mA) or direct current amperes (DCA), which are specifically designed for measuring current in a circuit. By selecting this setting, the meter is configured to measure the flow of electric charge, allowing for a precise reading of the current's strength in either standard amperes or in smaller units (milliamperes), depending on the expected range of the current to be measured.

Using the DCA setting is critical as it ensures that the meter is interpreting the electrical signals as a flow of direct current rather than voltage or resistance, which would yield inaccurate results or potentially damage the meter if used incorrectly. Therefore, selecting mA or DCA is essential for successful and safe measurement of DC amperage in electrical circuits.
