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
