SAFETY INSTRUCTIONS
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 GDS-1000B or to
other properties.
DANGER High Voltage

SAFETY INSTRUCTIONS
This chapter contains important safety
instructions that you must follow during
operation and storage. Read the following before
any operation to insure your safety and to keep
the instrument in the best possible condition.
Safety Symbols
These safety symbols may appear in this manual or on the GDS1000B.

GDS-1000B Series User Manual
Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.
General
Guideline
CAUTION
Make sure the BNC input voltage does not
exceed 300Vrms.
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 any heavy object on the GDS-
1000B.
Avoid severe impact or rough handling that
leads to damaging the GDS-1000B.
Do not discharge static electricity to the GDS-
1000B.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not perform measurement at a power source
or building installation site (Note below).
Do not disassemble the GDS-1000B unless you
are qualified.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
GDS-1000B falls under category I.
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.

SAFETY INSTRUCTIONS
Power Supply
WARNING
AC Input voltage: 100 - 240V AC, 50 - 60Hz,
auto selection. Power consumption: 30 Watts.
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.
Cleaning the
GDS-1000B
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh materials
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%, 40°C or below; ≤45%,
41°C ~ 50°C
Altitude: < 2000m
Temperature: 0°C to 50°C
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The GDS-1000B 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.

instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

Power cord for the United Kingdom
When using the oscilloscope in the United Kingdom, make sure the
power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2 should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.
