Page 9: Safety Notices And Information
Preparation for Use Safety Notices and Information Read this Operation Manual thoroughly before using the instrument to become familiar with its operations and capabilities. Visually inspect instrument before using. Do not use if unit appears damaged or with any part of the case removed. - Page 10 Preparation for Use CAUTION RISK OF INCORRECT READING Do not use when AC or DC voltages exist. Excessive voltage could result in an incorrect reading, or in more extreme cases, a blown fuse that will result in incorrect readings and need for repair. Do not use on reactive loads exceeding 2mH or 100uF.
