The 400A AC TRMS Clamp Meter is a professional digital clamp meter designed for accurate current and voltage measurements in industrial, commercial, and residential applications. It features True RMS measurement technology for precise readings on both sinusoidal and non-sinusoidal waveforms. The device supports AC current up to 400A, AC voltage up to 1000V, and includes functions such as resistance, capacitance, frequency, temperature, continuity, diode testing, and non-contact voltage detection. With built-in VFD (Variable Frequency Drive) mode and overload protection, it is ideal for electrical troubleshooting and maintenance.
- True RMS Measurement : Ensures accuracy with distorted waveforms.
- Inrush Current Detection : Captures high startup currents (up to 400A).
- AC Current Ranges : Up to 400A (with 100mA resolution).
- Voltage Measurement : Up to 1000V AC/DC.
- Resistance & Capacitance Measurement : With auto-ranging function.
- Frequency & Duty Cycle Measurement : Up to 100kHz.
- Temperature Measurement : Using Type K thermocouple probe.
- Non-Contact Voltage Detection : For quick live circuit checks.
- Backlit LCD Display : For improved visibility in low-light environments.
- Data Hold & Flashlight : Freezes readings and illuminates dark areas.
- Relative (REL) Mode : Measures values relative to a stored reference.
- Auto Power Off : Conserves battery life after ~15 minutes of inactivity.
-
Safety Certified : Complies with IEC61010-1 safety standards (CAT II 600V).
