Maintenance
XW Warning
To avoid possible electric shock or personal
injury:
•Before each use, inspect the Current Clamp.
Look for cracks or missing portions of the
clamp housing and output cable insulating
cover and for loose or weakened
components. Pay particular attention to the
insulation surrounding the clamp jaws.
•Do not use a damaged Current Clamp. If a
clamp is damaged, tape it shut to prevent
unintended operation. A damaged clamp
under warranty will be promptly repaired or
replaced (at Fluke’s discretion) and returned
at no extra charge.
If the Current Clamp does not work or perform properly, use
the following steps to help isolate the problem:
1. Inspect the jaw mating surface for cleanliness. If any
foreign material is present, the jaw will not close properly
and measurement errors will result.
2. Verify that the function selection and range on the
Multimeter are correct and adjusted to the sensitivity of the
Current Clamp.
Cleaning
Periodically wipe the case with a damp cloth and mild
detergent.
WCaution
To avoid damaging the Current Clamp, do not use
abrasives or solvents to clean the clamp.
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.

AC Current Clamp
Introduction
The i5s (hereafter called the “Current Clamp”) is compatible
with any instrument that can accept a standard BNC connector
and is capable of ac millivolt measurements; the Current
Clamp can also be used with digital multimeters using a
BNC-to-dual banana plug adapter. The Current Clamp
produces an output of 400 mV ac per 1 A ac input level.

Safety Information
XW Read First: Safety Information
To ensure safe operation and service of the
Current Clamp, follow these instructions:
•Read the operating instructions before use and
follow all safety instructions.
•Use the Current Clamp only as specified in the
operating instructions, otherwise the clamp’s safety
features may not protect you.
•Adhere to local and national safety codes. Individual
protective equipment must be used to prevent shock
and arc blast injury where hazardous live conductors
are exposed.
•Do not hold the Current Clamp anywhere beyond the
tactile barrier, see Figure 1.
•Before each use, inspect the Current Clamp. Look for
cracks or missing portions of the clamp housing or
output cable insulation. Also look for loose or
weakened components. Pay particular attention to
the insulation surrounding the jaws.
•Never use the Current Clamp on a circuit with
voltages higher than 600 V CAT III.
•CAT III equipment is designed to protect against
transients in equipment in fixed equipment
installations, such as distribution panels, feeders
and short branch circuits, and lighting systems in
large buildings.
•The Clamp is designed for use on insulated
conductors only. Use extreme caution when working
around bare conductors or bus bars. Contact with
the conductor could result in electric shock.
•Use caution when working with voltages above
60 V dc or 30 V ac rms. Such voltages pose a shock
hazard.

Instrument Compatibility
The Current Clamp is compatible with any Fluke Multimeter or
any other current measurement device that has the following
features:
•BNC or Banana inputs
•Input accuracy of 1 % or better to take full advantage of
the accuracy of the Current Clamp.
•Input impedance of > 1 M Ωin parallel with up to 47 pF
Note
Current input impedance on the Fluke 430 Series
Three-Phase Power Quality Analyzer is < 1 MΩ, but it
has a special calibration setting for the i5s to achieve
full accuracy.
Measurement Considerations
•Center the conductor inside the Current Clamp jaw.
•Make sure the Current Clamp is perpendicular to the
conductor.
•For optimal reading, make sure the conductor is centered
in the jaws of the Current Clamp.
Observe the following guidelines when making measurements:
•Avoid taking measurements close to other current-carrying
conductors.
Operation
To use the Current Clamp, refer to “Measurement
Considerations” and Figure 1:
1. If necessary, add a dual banana plug to BNC adapter to
the i5s BNC connector.
2. Connect the clamp cable to the instrument. If using an
adapter, use the common and volts inputs of the meter
and switch it on.
3. Make sure the measurement instrument is set to the
proper range.
4. Make sure the arrows on each side of the Current Clamp
face towards the load of the circuit.
5. Open the Current Clamp jaw by pushing the release
button toward the jaw until the latch has cleared the
barrier, then press down to open the jaw.
6. Connect the Current Clamp jaws around the insulated
conductor to be measured and release the button. Ensure
that the release button has returned to the original position
to resume the circuit testing.
XW Warning
To avoid shock or personal injury, keep fingers
behind the tactile barrier, see Figure 1.
