Safety Guidelines
General
Guideline
• 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 re and electric shock.
• Do not place heavy objects on the oscilloscope.
• Avoid severe impact 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 vent.
• Do not perform measurements at power sources and building installation sites
(Note below).
• The oscilloscope should only be disassembled by a qualied technician.
(Measurement categories) EN 61010-1:2001 species the measurement
categories and their requirements as follows. The unit falls under category II.
• Measurement category IV is for measurement performed at the source of a
low-voltage installation.
• Measurement category III is for measurement performed in a building
installation.
• Measurement category II is for measurement performed on circuits directly
connected to a low voltage installation.
• Measurement category I is for measurements performed on circuits not directly
connected to Mains.
