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 clamp on a circuit with voltages higher than 600V CAT III.
Use extreme caution when working around bare conductor or bus bars. Contact
with the conductor could result in electric shock.
Use caution when working with voltages above 60V or 30V ac. Such voltages
pose a shock hazard.
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.
Measurement Considerations
Center the conductor inside the Current 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 Current Clamp.
Observe the following guidelines when making measurements :
Avoid taking measurements close to other current carrying conductors.
Operation
To use the AC Current Adaptor, refer to “Measurement Considerations” and
Figure 1.
1. Connect the clamp cable to the instrument.
2. The arrow on the top of the clamp must face towards the load of the circuit.
3. Connect the current clamp jaws around the conductor to be measured.
