Introduction

2 INTRODUCTION

The Amprobe AC F 3000 AK is an AC currentprobe utilizing Rogowski

principle.The Amprobe A C F3000 AK can be used to measure AC current

up to 3000 A when used with a DMM,oscilloscope,orotherrecording

instruments.The flexible measuring head allows currentmeasurements on

conductors thatare hard to reach orinaccessible using typicalclamp-on

currentprobes.

The Amprobe A C F3000 AK provides a low-voltage,(3 V AC),output

proportionalto the currentbeing measured.Three selectable ranges

provide directreadings for30 A,300 A,and 3000 A full scale.

Operation

4 OPERATION

4.1 BATTERY INSTALLATION

Never replace batteries with flexible measuring head installed on

conductor to be tested or outputconnected to a display device.

Never operate the unitwithoutthe battery cover fitted.

The Amprobe A C F3000 AK requires two AA MN1500 LR6 alkaline

batteries foroperation.The battery compartmentis accessed from the

rearof the electronics enclosure.

The batteries mustbe replaced when the LED is lit continuously orfails to

lightup.Ensure thatthe Amprobe A C F3000 AK currentprobe is away

from any currentcarrying conductorand the outputis disconnected from

any otherequipment.

Using a coin ora similartoolturn the battery lock ¼turn until the dot

aligns with the unlock symbol.The battery covercan now be removed.

Install the batteries ensuring thatcorrectpolarity is observed.Replace the

battery coverand turn the battery lock until the dotaligns with the lock

symbol.

4.2 MEASURING CURRENT WITH THE AMPROBE

ACF3000 AK

Read safety section ofinstructions before operating this product

Ensure conductor to be tested is de energised.

Connectthe outputof the electronics to the VOLTS inputof the DMM or

otherdata recording device.
