AC/DC Current Probe
Instruction Sheet
Introducing The Current Probe
• The Fluke 80i-110s is a clamp-on AC/DC Current Probe that
reproduces current waveforms found in modern commercial and
industrial power distribution systems. The probe's performance
is optimized for accurate reproduction of currents at line
frequency and up to the 50th harmonic waveform. The 80i-110s
is also compatible with any instrument capable of millivolt
measurements. The Current Probe (shown in Figure 1) provides
the following benefits:
• Accurate AC, DC and AC+DC current measurements for
Electrical, Electronic and Automotive applications.
• Shielded for high noise immunity around electronic motor drives
and ignition systems.
• Wide measurement range from 50 milliamps to 100 amps,
useful to 10 milliamps.
• Jaw shaped for easy access to cramped spaces.
• Safety-designed 600 volt insuIated BNC - compatible with Fluke
ScopeMeter® test tools, Power Harmonic analyzers, and
oscilloscopes.
• Selectable output of 10 millivolts per 1 amp for the 100 A range,
and 100 millivolts per 1 amp for the 10 A range.

Warning
To avoid electrical shock, unclamp the current probe
from any conductor, and disconnect the scopemeter
test tool or any other measurement device before
installing or replacing the battery.
At first use, remember to install the battery. Referring to Figure 2,
use the following procedure to install the battery:
1. Be sure that you have unclamped the Current Probe from any
conductor and have disconnected the ScopeMeter test tool or
any other measurement device.
2. Be sure that the Current Probe is in the OFF position.
3. Locate the battery cover on the handle. (see Figure 2.) Loosen
the screw with a flat-blade screwdriver.
4. Slide the battery cover away from the Current Probe.
5. Install the battery (IEC 6LR61) as shown in Figure 2. Arrange
the battery leads so that they will not be pinched between the
handle bottom and the battery cover.

Instrument Compatibility
The 80i-110s is compatible with any Fluke ScopeMeter test tool,
Power Harmonics Analyzer, Oscilloscope, Multimeter, or other
voltage measurement device that has the following features:
• BNC input connector. A BNC-to-banana adapter (order
PM9081/001 from Fluke) can also be used with standard inputs
on a digital multimeter (DMM).
• Input accuracy of 2% or better to take full advantage of the
accuracy of the probe.
• Input impedance of greater than or equal to 1 MΩin parallel with
a maximum of 100 pF.
• A passband of more than four times the frequency of the
waveform to be measured.
Using The Current Probe
To use the Current Probe, follow these instructions:
1. Connect the 80i-110s Current Probe to the desired input on the
measuring instrument. When the ScopeMeter test tool or an
oscilloscope is used, it must have DC coupled input. When you
are using a digital multimeter, use the BNC-to- banana adapter
(PM9081/001) to connect the probe to the input.
2. On the Current Probe, select the least sensitive range (10
mV/A). Ensure that the green ON-indicator lights. See Figure 4
for selector switch and green On indicator locations.
3. On the Current Probe, rotate the ZERO thumbwheel to adjust
the probe reading to zero. See Figure 4 for the ZERO rotary
knob location.
4. Select the appropriate probe sensitivity on your ScopeMeter
test tool or oscilloscope.
5. Clamp the Current Probe around the conductor; be sure that
the arrow marked on the jaw of the Current Probe points
toward the correct orientation. (see Figure 3.)

6. Observe the current value or waveform on your display or the
current value readout on the multimeter.
7. On the ScopeMeter test tool, adjust the vertical range knob
and time division knob for the best display.
8. If the red OL-indicator lights, the Current Probe is in overload
mode.
9. At completion, be sure to set the range selection switch to OFF
again. A measuring setup using the Current Probe and a
ScopeMeter test tool is shown in Figure 4.

Measurement considerations
Observe the following guidelines for positioning the Current Probe
Jaws:
• Center the conductor inside the probe jaws.
• Make sure the probe is perpendicular to the conductor.
• Make sure that the arrow marked
on the jaw of the
Current Probe points toward the correct direction.
Observe the following guidelines when making measurements:
• If possible, avoid measurements close to other current-
carrying conductors.
• On the Current Probe, the 100 mV/A range offers the best
accuracy.
Maintenance
Before each use, assure continued safety by inspecting the probe.
Look for cracks or missing portions of the probe housing and output
cable insulating cover and for loose or weakened components. Pay
particular attention to the insulation surrounding the probe jaws. If a
probe fails this inspection, tape it shut to prevent unintended
operation. To check probe performance, complete the "Performance
Verification" procedure.
Warning
These servicing instructions are for use by qualified
personnel only. To avoid electric shock, do not
perform any servicing procedures unless you are
qualified to do so. Read the information titled "Safety
Information" at the beginning of this instruction sheet
before proceeding.
Repairs or servicing not covered in this Users Manual should be
performed only at a Fluke Service Center. A probe under warranty
will be promptly repaired or replaced (at Fluke's discretion) and
returned at no charge.
Cleaning and storage
Periodically wipe the case with a damp cloth and detergent; do not
use abrasives or solvents. Open the jaws and wipe the magnetic
pole pieces with a lightly oiled cloth. Do not allow rust or corrosion
to form on the magnetic core ends. If the probe is not used for
periods of longer than 60 days, the battery should be removed and
stored separately.
Performance verification
Verify probe accuracy with the test setup shown in Figure 5.
Required test equipment is defined in Table 1. Toroid coil
construction is illustrated in Figure 6.
Do the following to verify the probe accuracy:
1. Set up Connection.
2. Make the checks called for in Table 2 (100 mV/A).
3. Make the checks called for in Table 3 (10 mV/A).

If Your Current Probe Does Not Work
If the 80i-110s does not perform properly, use the following steps to
help isolate the problem:
1. Test the battery: be sure that the green ON-indicator lights
when you select the 10 mV/A range or the 100 mV/A range.
2. Inspect the jaw mating surface for cleanliness. If any foreign
material is present, the jaws will not close properly and errors
will result.
3. Verify that the probe is zeroed properly. For zeroing be sure
that the ScopeMeter test tool or oscilloscope is DC-coupled.
4. Verify that the function selection on the ScopeMeter test tool or
oscilloscope is correct, i.e., the display vertical resolution is not
too low or too high.
