Smart Digital Multimeters

Auto intelligent recognition (AUTO mode) – automatically identifies the measurement type (voltage, current, resistance, etc.) 

True RMS (T-RMS) measurement – provides accurate AC voltage and current readings on non-sinusoidal waveforms found in VFDs, LED drivers, and switching power supplies.

NCV (Non-Contact Voltage) detection – safely identifies live AC voltage through insulation without touching bare conductors.

Data retention (HOLD function) – freezes the current reading on the display for easy recording in hard-to-reach or poorly lit areas.

Over range prompt (OL indication) – clearly alerts when the measured value exceeds the range to prevent misinterpretation.

Status bar display with auto shut-down indicator (iOff) – shows battery status, range, and auto power-off countdown at a glance.

Low voltage prompt – warns when battery is low to ensure measurement reliability before critical tests.

Line of fire (live wire) judgment – distinguishes live (fire) wires from neutral (zero) wires for safe electrical troubleshooting.

Built-in flash light lighting – illuminates dark breaker panels, junction boxes, and equipment cabinets for hands-free operation.

Type-C charging – rechargeable via standard USB-C cable; no need to buy or replace 9V batteries.

On/off buzzer (continuity test) – emits a clear audible tone when resistance ≤50Ω for quick cable and circuit checks.

Diode test function – measures diode forward voltage with 3V output and <3mA current for LED and semiconductor testing.

Wide DC/AC voltage range (0V~600V) – covers low-voltage electronics to standard household and industrial power systems.

DC/AC current measurement (0mA~600mA) – ideal for low-current circuits, sensors, control loops, and small appliances.

Resistance measurement (0.1Ω~20MΩ) – from short circuit detection to high-value resistor checks.

Capacitance measurement (0.01nF~100mF) – tests capacitors from small ceramic discs to large electrolytic filter caps.

Frequency measurement (10Hz~1MHz) – checks signal generators, oscillators, and VFD output frequencies.

Non-redundant design – every function serves a practical purpose; no useless or gimmicky features.

Versatile and easy to use – suitable for electricians, HVAC technicians, automotive diagnostics, and hobbyist electronics.

Compact all-in-one tool – replaces multiple testers (voltage, current, resistance, capacitance, frequency, continuity) with one handheld device.
