Frequently Asked

Common Questions & Answers

How do mechanical shutters work?

Physical shutters mechanically block input jacks not needed for the current dial mode, preventing accidental cross-connection and protecting internal fuses.

Why is True RMS testing needed?

True RMS delivers accurate AC readings on distorted or irregular non-sinusoidal waveforms found in modern electronic power supplies and motor drives.

Can it measure extreme temps?

Yes, the included K-type thermocouple probe reliably measures temperatures ranging from -20°C up to 1000°C for HVAC and automotive work.

Is this tool auto-range?

Yes, it automatically detects and selects the optimal testing range for quick measurements, while manual override is available when specific test ranges are preferred.

How does NCV function work?

The built-in Non-Contact Voltage sensor detects live AC voltage without touching bare wires, providing an extra layer of quick safety checks before you begin.

What is the count resolution?

The 40,000-count screen delivers high-resolution data display, catching subtle voltage fluctuations standard meters miss.

Is a carry pouch included here?

Yes, a durable protective carrying case is included along with test leads, a temperature thermocouple probe, and an English instruction manual.

Can it test industrial capacitors?

Yes, with a wide capacitance range from 9.999nF up to 99.99mF, it handles both small electronics PCB capacitors and large HVAC motor start capacitors effortlessly.
