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.
