2. Overview

This meter is a double impedance high-performance true RMS digital clamp meter, which integrates multiple functions, making your work easier, more efficient, and safer.

It can measure AC/DC voltage, AC/DC current, frequency, duty, resistance, capacitance, temperature, diode, NCV, VFD, inrush current, etc.

High Input Impedance Voltage Measurement:

When measuring in a circuit, it has little effect on circuit performance. This is the desired effect for most voltage measurement applications and is especially important for sensitive electronic or control circuits.

Low Input Impedance Voltage Measurement (LoZ):

It can safely troubleshoot sensitive electronic or control circuits and circuits that may contain false voltages, and can more reliably determine whether there is a voltage on the circuit.
