Introduction

Overview

This AC leakage clamp meter allows you to measure from minute leakage current to load

current.

Accurately measuring minute leakage current

• The 6.000 mA range is incorporated to ensure the measurement with a high resolution of

1 µA.

• High permeability magnetic material is used for the jaws.

E󰀨ects of external electromagnetic noise are minimized to enable the measurement with

high reproducibility.

Measuring a wide range of current from leakage current to load

current

• Accuracy ranging from 0.060 mA to 200.0 A is ensured.

• Frequency band ranging from 15 Hz to 2 kHz
