Battery Installation 
XWWarning 
To avoid electric shock or personal injury: 
•  Never replace batteries with the flexible 
measuring head installed on the conductor to 
be tested or with the output connected to a 
display device. 
•  Never operate the unit without the battery cover 
installed. 
The Probes require two AA/MN1500/LR6 alkaline batteries for 
operation. The battery compartment is accessed from the rear 
end of the electronic enclosure. 
The batteries must be replaced when the LED is lit continuously 
or when it fails to light up. Ensure that the Probe is away from 
any current carrying conductor and also that the output is 
disconnected from other equipment. 
To install the battery: 
1.  Use a coin or a similar tool to turn the battery lock (¼ 
turn) until the dot aligns with the unlock symbol. 
2.  Remove the battery cover. 
3.  Install the batteries ensuring that correct polarity is 
observed. 
4.  Replace the battery cover and turn the battery lock until 
the dot aligns with the lock symbol. 
External Power Supply (i3000s Models) 
An optional Class II external power supply is available from 
Fluke. The power supply is designed to ensure that the Probe 
continues to meet its specified safety standards. The usage of a 
power supply from another vendor is not recommended. 
XWWarning 
To avoid electric shock or injury, never connect or 
disconnect the external power supply with the 
flexible measuring head installed on the conductor 
or with the output connected to a display device.
