T
The 20A/200A Current Clamp Set (the Clamp) has been
designed for applications with Fluke 1735 and Fluke 1740
series products for accurate non-intrusive measurement of ac
currents. Using latest technologies (integrated memory for
calibration data) provides current ranges from 0.5 A to 200 A in
a frequency range of 40 Hz to 5 kHz.

Safety Instructions
Please read this section carefully. It will familiarize you with the
most important safety instructions for handling the Probe. In
this instruction sheet, a Warning identifies conditions and
actions that pose hazard(s) to the user. A Caution identifies
conditions and actions that may damage the calibrator or the
test instruments.

Warning
The Clamp may only be used and handled by
qualified personnel. To avoid personal injury,
follow these precautions:
•
To avoid electric shock, use caution during
installation; high voltages and currents may
be present in circuit under test.
•
Do not use the Clamp if damaged. Always
connect to display device before it is installed
around the conductor.
•
Use the Clamp only as specified in the
operating instructions; otherwise the safety
features may not protect you.
•
Adhere to local and national safety codes.
Individual protective equipment must be used
to prevent the shock and arc blast injury
where hazardous live conductors are
exposed.
•
Before each use, inspect the Clamp. Look for
cracks or missing portions of the housing or
output cable insulation. Also look for loose or
weakened components.

Use caution when working with voltages
above 60 V dc, 30 V ac rms or 42 V ac peak.
Such voltages pose a shock hazard.
This Clamp is considered to be used in 600
CAT III environments. CAT III equipment is
designed to be used in distribution panels,
feeders and short branch circuit, and the
lighting system in large buildings.
Do not use the Clamp in damp or wet
environments or in locations that hazardous
gases exist.
Do not hold the Current Clamp anywhere
beyond the tactile barrier.
De-energize circuit during installation and
removal of Clamp.
Connect the Clamp to the current input jack of the
product. Verify that the product has recognized that a
current Clamp is connected.
In case of uninsulated conductors, de-energize the
circuit before placing the clamp. Re-energize the
circuit.
Observe and take measurements as required.
Positive output indicates that the current flow is in the
direction shown by the arrow on the Clamp.
In case of uninsulated conductors, de-energize the
circuit before removal of the Clamp.

Measurement Considerations
Observe the following guidelines when making measurements:
•
Center the conductor inside the Clamp jaw.
•
Make sure the Clamp is perpendicular to the conductor.
•
For optimal reading, make sure the conductor is positioned
between the alignment marks on the jaws of the Clamp.
•
Avoid taking measurements close to other current-carrying
conductors.
