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.

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.
