80i-110s Instruction Manual 3
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 sys-
tems. 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.

USING THE CURRENT PROBE SAFELY
ATTENTION
Carefully read the following safety information before attempting to operate
or service the Current Probe.
•Never use the probe on circuits rated higher than 600V in Installation
Category II (CAT II) or 300V in Installation Category III (CAT III). (See
"Safety Specifications".) Use extreme caution when clamping around
uninsulated conductors or bus bars.
•Keep your fingers off the probe jaws.
•Check the magnetic mating surfaces of the probe jaws; these should be free
of dust, dirt, rust, and other foreign matter.
•Do not use a probe that is cracked, damaged, or has a defective cable. Such
probes should be made inoperative by taping the clamp shut to prevent
operation.
In this Users Manual, a WARNING identifies conditions and actions that pose haz-
ard(s) to the user. A Caution identifies conditions and actions that may damage
the current probe. International electrical symbols used are explained below.

12 80i-110s Instruction Manual
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. ClamptheCurrentProbearoundtheconductor;besurethatthearrowmarked
on the jaw of the Current Probe points toward the correct orientation. (see
Figure 3.)
Figure 3. Orientation of the Current Probe

80i-110s Instruction Manual 13
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.

80i-110s Instruction Manual 15
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 "USING THE CURRENT PROBE SAFELY"
AT THE BEGINNING OF THIS USERS MANUAL 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.
