Wipcool ADC400 Clamp Meter

True RMS clamp meter for measuring AC current up to 400 A without breaking the circuit, with a 28 mm jaw opening. With the test leads it also measures voltage up to 600 V, resistance and capacitance, and the NCV tip detects voltage without touching the conductor.

1. What it is used for

The ADC400 is a digital clamp meter with True RMS measurement. The jaws open to 28 mm, clamp around a single conductor and measure AC current up to 400 A. With the test leads connected, the meter measures AC and DC voltage up to 600 V, resistance, capacitance and frequency, tests continuity and diodes, and with a temperature probe it measures temperature.

The NCV tip on the jaws detects AC voltage in a socket or an insulated cable and indicates it with an audible signal, a red LED and segments on the display.

Current without breaking the circuit. The jaws clamp around the conductor and measure AC current up to 400 A, so you do not need to disconnect the installation to take a reading.
Low capacitance with REL correction. For capacitance below 100 nF, REL mode subtracts the capacitance of the test leads themselves from the reading.
Warnings at high values. From 30 V AC or 60 V DC the display shows a high-voltage warning, and at currents from 400 A the meter gives an audible signal and the alarm symbol flashes.
