What are some tests or measurements that can be made using a Voltage Ohm Meter (VOM)?

A Voltage Ohm Meter (VOM), commonly known as a multimeter, is primarily designed for measuring electrical properties such as voltage and resistance. Option B highlights the capabilities of a VOM, which include measuring both alternating current (AC) and direct current (DC) voltages, as well as testing for opens (broken or disconnected circuits) and shorts (unintended connections that can cause current to flow where it shouldn’t).

Being able to measure AC and DC voltages is crucial for electrical troubleshooting because it allows technicians to verify that power is present and that the correct type of power is being delivered to devices. The ability to test for opens and shorts is critical as these conditions can significantly affect the performance of electrical systems.

The other options include measurements that are outside the primary function of a VOM. Frequency and amplitude measurements typically require specialized equipment like an oscilloscope. While capacitance and battery life checks can sometimes be performed by certain models of multimeters, they are not the primary function of a standard VOM and may require additional settings or equipment. Lastly, signal interference and quality assessment are also tasks that usually necessitate more advanced diagnostic tools than a standard VOM.
