WX Warning 
The Probe may only be used and handled by 
qualified personnel. To avoid electric shock or 
personal injury, follow these precautions: 
•Do not apply to or remove from hazardous 
live conductors without taking additional 
protective measures. 
•High voltages and currents may be present in 
adjacent circuits under test. 
•Do not use the Probe if damaged. Always 
connect to display device before it is installed 
around the conductor. 
•Use the Probe 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 Probe. 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. 
•Equipment is considered to be used in 600 V 
CAT IV and 1000 V CAT III environment. 
CAT IV equipment is designed to be used at 
the source of distribution system up to the 
energy-meter within the installation. CAT III 
equipment is designed to be used in 
distribution panels, feeders and short branch 
circuits, and the lighting system in large 
buildings. 
•Do not use Probe in damp or wet 
environments or in locations that hazardous 
gases exist. 
Operating Instructions 
1. Connect the Probe to the product current input jack. 
2. Wear protective gloves or de-energize the circuit and 
place the Probe around the conductor under test. Re-
energize the circuit. 
3. Observe and take measurements as required. 
Positive output indicates that the current flow is in the 
direction shown by the arrow on the Probe. 
4. Wear protective gloves or de-energize the circuit 
before removal of the Probe. 
Cleaning 
Clean the Probe periodically by wiping it with a damp cloth and 
detergent. Do not use abrasive cleaners or solvents. Do not 
immerse the Probe in liquids.
