Safety Instructions
Please read this section carefully. It will familiarize you with the
most important safety instructions for handling the Clamp. 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 Clamp or the test instruments.
WX 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.
• Use of this equipment is designed to CAT III
standards. CAT III equipment is designed to
protect against the transients in the equipment
in fixed equipment installations, such as
distribution panels, feeders and short branch
circuits, and the lighting systems in large
buildings.
• Do not use the Clamp in wet environments or in
locations that hazardous gases exist.
• Do not hold the Clamp anywhere beyond the
tactile barrier, see Figure 1.

Operating Instructions
1. Connect the Clamp to the 1750 current input jack.
Verify that the 1750 has recognized that a current
Clamp is connected.
2. Place the Clamp around the conductor under test.

3. Observe and take measurements as required. Positive
output indicates that the current flow is in the direction
shown by the arrow on the Clamp.
Maintenance
Cleaning
Clean the Clamp periodically by wiping it with a damp cloth and
detergent. Do not use abrasive cleaners or solvents. Do not
immerse the Clamp in liquids.
