Introduction; Specifications; Electrical Data; General Data - GMC-I PRO SyS CP 305 Mode D'emploi

2. INTRODUCTION

The CP 305 current probe has been designed for use
with multimeters and oscilloscopes for accurate, non-
intrusive measurement of
waveform currents.
Using advanced Hall Effect technology the CP 305 can
measure currents up to 450A peak over the frequency
range of DC to 20 kHz.
These features make it a powerful tool for use with
inverters, switch mode power supplies, industrial
controllers and other applications requiring current
measurement and/or waveform analysis.
