You have selected an instrument which provides you with a high level of safety. The RISH Insu 20 Analog-Digital Insulation Tester is manufactured in compliance with safety regulations IEC 61010-1/EN 61010-1/VDE 0413 part 1. When used for its intended purpose, safety of the operator, as well as that of the instrument, is assured. In case of incorrect use or careless handling, the safety of both user and instrument is not assured. To maintain the safe and proper condition of the instr ment and to ensure its safe operation, it is absolutely necessary to carefully and completely read these operating instructions before using the instrument. These instructions must be followed in all respects. Observe the following safety precautions : The instrument must be operated only by persons who understand the danger of shock hazards and know how to apply safety precautions. Shock hazards exist anywhere, where voltages of more than 30 V may occur. Do not work alone in shock hazardous environment while carrying out measurement. The maximum allowable voltage between any terminal sockets and earth is equal to 600 V for voltage and 1000V for Insulation resistance measurement. Verify that the test leads are in good condition, e.g. no cracked insulation, no open circuits in the leads or connectors. Measurements under moist ambient conditions are not permitted. Do not exceed the permissible overload limits of the measuring ranges. Limit values can be found in the table in “12. Specification”.
