The digital multimeter, also known as a DMM, is one of the most practical and useful electrical test instruments on the market today. Digital multimeters are the best meters available that are capable of working with energized, as well as de-energized, electrical circuits. There are a variety of functions that can be helpful to both amateur and professional users such as measuring AC and DC voltages and currents, continuity, resistance, capacitance, diodes, Ohms law and power formula, frequency and duty cycle.
For safety reasons, the tips below should be considered when selecting a Digital Multimeter:
- Fused current inputs (high energy fuses)
- Overload protection on the ohms function
- Test leads that have shrouded connectors and finger guards
- Recessed input jacks
- Independent certification
