Safety GuidelinesGeneralGuidelineCAUTION Make sure the BNC input voltage does notexceed 300V peak. Never connect a hazardous live voltage to theground side of the BNC connectors. It mightlead to fire and electric shock. Do not place heavy objects on the oscilloscope. Avoid severe impact or rough handling thatmay damage the oscilloscope. Avoid discharges of static electricity on or nearthe oscilloscope. Use only mating connectors, not bare wires, forthe terminals. Do not block the cooling fan vent. Do not perform measurements at power sourcesand building installation sites (Note below). The oscilloscope should only be disassembledby a qualified technician.(Measurement categories) EN 61010-1:2001 specifies themeasurement categories and their requirements as follows. TheGDS-1000A falls under category II. Measurement category IV is for measurement performed at thesource of a low-voltage installation. Measurement category III is for measurement performed in abuilding installation. Measurement category II is for measurement performed oncircuits directly connected to a low voltage installation. Measurement category I is for measurements performed oncircuits not directly connected to Mains.Power SupplyWARNING AC Input voltage: 100 ~ 240V AC, 47 ~ 63Hz The power supply voltage should not fluctuatemore than 10%. Connect the protective grounding conductor ofthe AC power cord to an earth ground.
