INTRODUCTION
The Fluke 80i-410 DC/AC Current Probe is a battery-powered
· clamp-on current probe that is used with a voltmeter to measure de
or ac currents up to 400 amps. Each jaw of the probe contains half of
a magnetic core. The jaws clamp around a conductor allowing
current measurements without breaking the circuit. A Hall sensor

the current being measured. An amplifier circuit generates an output
signal of 1 mV per amp. Demagnetizing (degaussing) is accom-
plished by manually snapping the jaws.

VOLTMETER COMPATIBILITY
The 80i-41 O DC/ AC Current Probe is compatible with any voltmeter,
multimeter, or other voltage-measuring instrument that has the
following features:
• Input jacks that accept Fluke safety-designed shrouded
bararia plugs.
• Rang "' and resolution capable of displaying 1 mV of
output per amp of measured curre11t.
• Voltmeter accuracy (uncertainty) of 0.75% or better to
take full advantage of the accuracy of the probe.
• Input impedance of 1 MO, 100 pF or greater. (See the
Load Impedance specifications for operation with lower
impedance instn 1T1ents.)
When the probe is making
c.
measurement, the current-carrying
conductor is not brokan and remains electrically isolated from the
probe's output. As a result, the probe's output common may be
either floated (isolated) or grC'underi.
BATTERY INSTALLATION
The 80i-410 DC/AC Current Probe requires two 1.5V, AAA size
batteries for operation. Install the batteries as follows:
1. Use your thumbnail to raise the latch and open the
battery compartment (see FiQure 1).
2. Observe the polarity man-:ings on the inside of the
battery door. Note that the polarity for each batterv is the
reverse of the other.
