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 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 qualified technician.
(Measurement categories) EN 61010-1:2001 specifies the
measurement categories and their requirements as follows. The
GDS-1000A 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.
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.
