7 SAFETY INSTRUCTION This chapter contains important safety instructions that should be followed when operating and storing the oscilloscope. Read the following before any operation to ensure your safety and to keep best condition for the oscilloscope. Safety Symbols These safety symbols may appear in this manual or on the oscilloscope. WARNING Warning: Identifies conditions or practices that could result in injury or loss of life. CAUTION Caution: Identifies conditions or practices that could result in damage to the oscilloscope or to other objects or property. DANGER High Voltage Attention: Refer to the Manual Protective Conductor Terminal Earth (Ground) Terminal User Manual – SEFRAM 53X2DC 8 Safety Guidelines General Guideline CAUTION • Make sure the BNC input voltage does not exceed 300V peak. • Never connect a hazardous live voltage to the ground side of the BNC connectors. It might lead to fire and electric shock. • Do not place heavy objects on the oscilloscope. • Avoid severe impacts or rough handling that may damage the oscilloscope. • Avoid discharges of static electricity on or near the oscilloscope. • Use only mating connectors, not bare wires, for the terminals. • Do not block the cooling fan opening. • Do not perform measurement at power source and building installation site (Note below). • The oscilloscope should only be disassembled by a qualified technician. (Measurement categories) EN 61010-1:2001 specifies the measurement categories and their requirements as follows. The GDS-1000 falls under category II. • Measurement category IV is for measurement performed at the source of low-voltage installation. • Measurement category III is for measurement performed in the building installation. • Measurement category II is for measurement performed on the circuits directly connected to the low voltage installation. • Measurement category I is for measurements performed on circuits not directly connected to Mains.

9 Power Supply WARNING • AC Input voltage: 100 ~ 240V AC, 47 ~ 63Hz • The power supply voltage should not fluctuate more than 10%. • Connect the protective grounding conductor of the AC power cord to an earth ground. Fuse WARNING • Fuse type: T1A/250V • To ensure fire protection, replace the fuse only with the specified type and rating. • Disconnect the power cord before replacing the fuse. • Make sure the cause of fuse blowout is fixed before replacing the fuse. Cleaning the oscilloscope • Disconnect the power cord before cleaning the oscilloscope. • Use a soft cloth dampened in a solution of mild detergent and water. Do not spray any liquid into the oscilloscope. • Do not use chemical containing harsh products such as benzene, toluene, xylene, and acetone. Operation Environment • Location: Indoor, no direct sunlight, dust free, almost non-conductive pollution (Note below) • Relative Humidity: < 80% • Altitude: < 2000m • Temperature: 0°C to 50°C User Manual – SEFRAM 53X2DC 10 (Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. the oscilloscope falls under degree 2. Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”. • Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no influence. • Pollution degree 2: Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected. • Pollution degree 3: Conductive pollution occurs, or dry, non-conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled. Storage environment • Location: Indoor • Relative Humidity: < 85% • Temperature: 0°C to 50°C
