A handheld digital multimeter is a multifunctional electronic measuring tool that is widely used in electronic engineering, power maintenance, industrial testing and other fields. The following are its main uses and features:

• Voltage Measurement: Supports DC voltage (DCV) and AC voltage (ACV) measurements, with ranges from millivolts to kilovolts.
• Current Measurement: Capable of measuring DC current (DCA) and AC current (ACA), with some models supporting short-term measurements of high currents up to 20A.
• Resistance Measurement: Accurately measures circuit impedance using the ohm range (Ω), helping to locate open circuits or contact failures.

• Continuity Test: Quickly determine circuit continuity using the beeper function.
• Component Test: Select models support diode, transistor (HFE) and capacitor measurements.
• Temperature Measurement: Advanced models equipped with a temperature sensor can directly measure temperature.

• True RMS Technology: Accurately measures non-sinusoidal AC signals.
• Environmental Adaptability: Select industrial-grade models operate in -40°C to 55°C environments.
• Safety Protection: Meets CAT III 1000V/CAT IV standards. 600V safety standard
• Data logging: Supports storage of tens of thousands of measurement data sets

• Non-contact voltage detection (Vsense): Detects AC voltage without physical contact
• Low impedance mode (ZLOW): Eliminates stray voltage interference
• Frequency response analysis: Select models can measure signal frequency and duty cycle
