Key benefits and uses of the Digital Multimeter: • Measuring electrical voltage (Voltage): To measure alternating current (AC) like home outlets, or direct current (DC) like batteries. • Measuring resistance (Resistance): To ensure the safety of wires and electronic components. • Measuring current (Current): To know the amount of electricity a specific device consumes. • Continuity test (Continuity): Emits a sound to ensure the wire is not cut and that current passes safely. • NCV feature (in C+ model): Allows you to detect the presence of electricity within walls or wires without needing to touch them (non-contact voltage detector). • Measuring transistor (hFE): A very useful feature for those interested in repairing delicate electronic boards. There are 4 units available.
