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. 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.

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. Operating Instructions 1. Connect the Clamp to the current input jack of the product. Verify that the product has recognized that a current Clamp is connected. 2. In case of uninsulated conductors, de-energize the circuit before placing the Clamp. 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 Clamp. 4. In case of uninsulated conductors, de-energize before removal of the Clamp.
