The FNIRSI DMC-100 is a True RMS clamp meter that measures AC and DC current up to 600A without breaking the circuit.

Clamp around a wire, read the current on screen. No need to disconnect anything.

What Does It Measure?

DC Voltage: up to 999.9V

AC Voltage: up to 750V

DC Current: up to 600A (clamp)

AC Current: up to 600A (clamp)

Resistance: up to 99.99MΩ

Capacitance: supported

Frequency: supported

Temperature: -55°C to 1300°C (probe included)

Diode testing: supported

Continuity: audible on-off test

True RMS measurement gives accurate readings on non-sinusoidal waveforms.

This matters when working with modern electronics, variable speed drives and LED lighting circuits.

25mm Jaw Opening

The clamp jaw opens to 25mm.

Fits around most household and light industrial cables.

Clamp around a single conductor to measure current flow.

Colour Display

The 2.0-inch TFT colour screen shows clear readings.

Resolution of 240 × 320 pixels.

Ten brightness levels adjust to different lighting conditions.

Three Measurement Modes

General measurement – standard meter readings

Waveform display – see the shape of AC signals

Power measurement – calculate power from voltage and current

Switch between modes depending on what you need to analyse.

Data Storage

Store up to 30 groups of measurement data.

Review saved readings later without writing them down.

Useful for comparing measurements across different circuits or time periods.

Rechargeable Battery

Built-in 1500mAh lithium battery.

Charges via USB Type-C.

No hunting for replacement batteries.

Auto power-off after 5, 15 or 30 minutes of inactivity to save charge.

Built-in Torch

LED torch helps when working in dark panels or dimly lit areas.

Always have light where you need it.

Compact and Portable

Dimensions: 193 × 74 × 32mm

Weight: 194g

Fits comfortably in your hand and your toolkit.

Customer Reviews (4.6 / 5 · 5 reviews)

Kevin ★★★★★

The jaws opened wide enough to clamp around a thick battery cable without any hassle, which was a relief. I used it to check a fluctuating DC motor circuit and the readings settled quickly, making troubleshooting straightforward. For the price, getting true RMS and 600A capacity feels like solid val

Benjamin ★★★★★

Finally got around to testing it on a 240V circuit and the AC/DC clamp read within 0.3A of my bench meter. The backlight makes it easy to see in my dim basement panel, too.

Chloe I. ★★★★★

Clamped it around the main feed to my subpanel and got a steady 47A reading in seconds, no need to pull any wires apart. The True RMS reading matched what my old inline meter showed, which was a relief. For the price I honestly expected flimsier jaws.
