Multimeters are used to measure the resistance of objects, as well as alternating current (AC) and direct current (DC) voltage and current. They can also measure the main parameters of transistors, the capacitance of capacitors, the inductance of inductors, voltage frequency, duty cycle, and the temperature of objects. Ultratech multimeters cover a wide range of usage scenarios. In terms of operation, they offer options such as manual ranging, auto-ranging, knob function switching, and button function switching. For different usage scenarios, they provide choices like home-use, pocket-sized, handheld, automotive, intelligent, and easy-to-use models, as well as true RMS (Root Mean Square) types. In terms of functionality, they include measurements of AC and DC voltage, AC and DC current, resistance, capacitance, admittance
