1. Safety Precautions This product complies with the requirements of the following European Community Directives: 2004/108/EG (Electromagnetic Compatibility) and 2006/95/EG (Low Voltage) as amended by 2004/22/EG (CE-Marking). Overvoltage category II; pollution degree 2. To ensure safe operation of the equipment and eliminate the danger of serious injury due to short-circuits (arcing), the following safety precautions must be observed.
* Do not operate the equipment near strong magnetic fields (motors, transformers etc.) * Keep hot soldering irons or guns away from the equipment. * Allow the equipment to stabilize at room temperature before taking up measurement (important for exact measurements). * Do not input values over the maximum range of each measurement to avoid damages of the meter. * Use caution when working with voltages above 35V DC or 25V AC. These Voltages pose shock hazard.
