Fluke 80i-110s Operating Manual

80i-110s

AC/DC Current Probe

Instructions

Introduction

The Fluke 80i-110s (the Probe or Product) is a clamp-on AC/DC Current
Probe that reproduces current waveforms found in commercial and industrial
power distribution systems. The Probe performance is optimized for accurate
reproduction of currents at line frequency and up to the 50
waveform. The 80i-110s is also compatible with any instrument capable of
millivolt measurements.

The Probe provides these 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 mA to 100 A, useful to 10 mA.

• Jaw shaped for easy access to cramped spaces.

• Tactile barrier (see Figure 1, item

• Safety-designed 600 V insuIated BNC - compatible with Fluke
ScopeMeter

oscilloscopes.

• Selectable output of 10 millivolts/1 amp for the 100 A range, and
100 mV/1 A for the 10 A range.

Warning

To prevent personal injury and for safe operation of the Product:

• Read all safety information before you use the Product.

• Carefully read all instructions.

• Do not use the Product if it is altered or damaged.

• Do not alter the Product and use only as specified, or the
protection supplied by the Product can be compromised.

• Comply with local and national safety codes. Use personal
protective equipment (approved rubber gloves, face
protection, and flame-resistant clothes) to prevent shock and
arc blast injury where hazardous live conductors are
exposed.

• Hold the Product behind the tactile barrier.

• Before each use, examine the Product. Look for cracks or
missing pieces of the clamp housing or output cable
insulation. Also look for loose or weakened components.
Carefully examine the insulation around the jaws.

• Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.

• Use the Clamp only on insulated conductors. Use caution
around bare conductors or bus bars. To prevent electrical
shock, do not touch the conductor.

Battery

Warning

To prevent electrical shock, unclamp the Probe from any
conductor, and disconnect the Scopemeter test tool or any
other measurement device before you install or replace the
battery.

Before the first use, install the battery. See Figure 2.
To install the battery:

1. Unclamp the Probe from any conductor and disconnect the
ScopeMeter test tool or any other measurement device.

2. Make sure that the Probe is in the OFF position.

3. Locate the battery cover on the handle and loosen the screw with a flat­blade screwdriver.

4. Slide the battery cover away from the Probe.

5. Install the battery (IEC 6LR61). Arrange the battery leads so that they
are not pinched between the handle bottom and the battery cover.

6. Reinstall the battery cover and secure the screw.

Warning

To prevent possible electrical shock, fire, or personal injury,
replace the batteries when the low battery indicator shows to
prevent incorrect measurements.

Compatibility

The Product is compatible with any Fluke ScopeMeter test tool, Power
Harmonics Analyzer, Oscilloscope, Multimeter, or other voltage measurement
device with these features:

• BNC input connector (PN PM9081/001 BNC-to-banana adapter) for

use 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 ≥1 MΩ in parallel with a maximum of 100 pF.

• A passband of more than four times the frequency of the waveform to

be measured.

Instructions

To use the Probe:

1. Connect the Probe to the 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 Probe, select the least sensitive range (10 mV/A). Make sure that
the green ON-indicator lights. See Figure 4 for selector switch and green
On indicator locations.

3. On the Probe, rotate the ZERO thumbwheel to adjust the 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 Probe around the conductor. Make sure that the arrow mark
on the jaw of the Probe points toward the correct orientation. See
Figure 3.

Figure 3. Current Probe Orientation

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 Probe is in overload mode.

9. At completion, set the range selection switch to OFF again. A

Measurement Guidelines

Use these guidelines to position the jaws:

• Center the conductor inside the jaws.

• Position the Probe perpendicular to the conductor.

• Make sure that the arrow marked on the jaw of the Probe

points toward the correct direction.

Use these guidelines to take measurements:

• If possible, avoid measurements close to other current-carrying

conductors.

• On the Probe, the 100 mV/A range offers the best accuracy.

Maintenance

Before each use, inspect the Probe. Look for cracks or missing portions of the
housing and output cable insulating cover and for loose or weakened
components. Pay particular attention to the insulation surrounding the jaws. If
a Probe fails this inspection, tape it shut to prevent unintended operation. To
check Probe performance, complete the Performance Verification procedure.

Warning

To avoid electric shock:

• Do not perform any service procedures unless you are
qualified to do so.

• Read the "Safety" information at the beginning of this
instruction sheet before proceeding.

If the Probe does not perform properly, use these 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, for example, the display vertical resolution is not
too low or too high.

Repairs or service not covered in this document must be performed only at a
Fluke Service Center. A Probe under warranty will be 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 long time periods (>60 days) the battery should be
removed and stored separately.

Accessories

An adapter accessory is required to use the Probe with a digital
multimeter. The BNC-to-Banana Adapter, Fluke Part PM9081/001, is
available to order.
