Use the product only as specified, or the protection supplied by the product can be compromised. Comply with local and national safety codes. Use personal protective equipment (approved rubber gloves, face protection, and flame-resistant clothes) to prevent shock and arc blast injury where hazardous live conductors are exposed. Hold the product behind the tactile barrier. Before each use, examine the product. Look for cracks or missing pieces of the clamp housing or output cable insulation. Also look for loose or weakened components. Carefully examine the insulation around the jaws. Do not exceed the Measurement Category (CAT) rating of the lowest rated individual component of a product, probe, or accessory. Use the Clamp only on insulated conductors. Use caution around bare conductors or bus bars. Do not touch the conductor. Do not touch voltages > 30 V ac rms, 42 V ac peak, or 60 V dc. Do not use the product around explosive gas, vapor, or in damp or wet environments. For more information about the category rating, see the 1750 Power Recorder Getting Started Guide.

Examine the jaw for a clean mating surface. If there is unwanted material, the jaw will not close correctly and will cause measurement errors. 2. Make sure that the function selection and range are correct on the Multimeter and adjusted to the sensitivity of the Current Clamp. Note A damaged clamp under warranty will be repaired or replaced (at Fluke's discretion) at no charge. Caution To prevent damage to the Current Clamp, do not use abrasives or solvents to clean the clamp. 2.5 % 1.5 % 1.0 % Open the jaws and clean the magnetic pole pieces with a lightly oiled cloth. Do not let rust or corrosion collect on the magnetic core ends. 1/5/2011 8:57:27 AM Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Fluke: I40S-PR
