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 dc 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 mounted
in a gap in the core senses the magnetic field produced by current
eing measured. An amplifier circuit generates an output signal of 1
N peramp. Demagnetizing (degaussing) is accomplishedby manu-
ally snapping the jaws.
SPECIFICATIONS
ELECTRICAL
Specified Current Range: 5 to 400A dc or ac
NOTE
When using this probe with a true-rms meter, the mini-
mum ac current is limited to the low end of the specified
ac mV range of the meter. For the following Fluke
meters, the minimum current input for specified ac
accuracy is as follows:
Fluke 45: 15A
Fluke 87: 204
8060A/8062A: 10A
Usable Current Range: 2 to 600A dc or ac
Output Signal: 1 mV per amp dc or ac
Accuracy (uncertainty): + (5% of reading + 2.5A), 5to 400A, dc to
62 Hz, for 1 year, 18 to 28°C (64 to 82°F),
probe demagnetized, conductor centered
Frequency Response: -7% at 400 Hz, -3 dB at 1200 Hz typical
Working Voltage: 660V rms maximum at input
Maximum Conductor Sizes: 1 ea 30 mm (1.18*“) diameter
2 ea 25 mm (0.98”) diameter
Load Impedance: >1 MQ, 100 pF (The probe's active circuit is
capable of driving impedances as low as 1 kQ
(chart recorders etc.). However, the battery test
indication will be incorrect (low) ifthe meter input
o impedance is less than 1 MQ.)
