SAFETY INSTRUCTIONS
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
the oscilloscope in the best condition.
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
GDS-1000A Series User Manual

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.
SAFETY INSTRUCTIONS
9
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 chemicals 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
(Pollution Degree) EN 61010-1:2001 specifies 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.

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:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
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.

preset positions.
3. Connect the power cord.
4. Press the power switch. The
display will become active
in approximately 10
seconds.
5. Reset the system by recalling
the factory settings. Press
the Save/Recall key, then
Default Setup. For details
regarding the factory
settings, see page38.
