Introduction; Specifications; Reference Conditions - LEM PR1200 ACI Mode D'emploi

1. INTRODUCTION

The PR 1200 range of current probes has been
designed for use with multimeters, recorders, power
analysers, safety testers etc. for accurate non intru-
sive measurement of AC current.
Using the latest transformer technology, the PR
1200 range can measure currents from 1 mA to
1200 A and are available with current or voltage
outputs.
The probes comply with the safety standards IEC
1010-2-032 for input and output circuits.
