SAFETY INSTRUCTIONS2.
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: Identifi es conditions or practices that could result in injury or loss of life.

General
Guideline
(Measurement categories) EN 61010-1:2001 specifi es the measurement categories
and their requirements as follows. The GDS-1000A falls under category II.
Power Supply AC Input voltage: 100 ~ 240V AC, 47 ~ 63Hz•
WARNING
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 fi 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 qualifi ed technician.•
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.
The power supply voltage should not fl uctuate more than 10%.•
Connect the protective grounding conductor of the AC power cord to an earth •
ground.

Cleaning the
oscillo-scope
Operation
Environment
To ensure fi re protection, replace the fuse only with the specifi ed type and •
rating.
Disconnect the power cord before replacing the fuse.•
Make sure the cause of fuse blowout is fi xed before replacing the fuse.•
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.
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 specifi es 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 infl uence.
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, nonconductive 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 identifi ed 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.

Accepts the DUT ground lead to achieve a common
ground.
Performs math operations (page 53).
Facilitates transferring waveform data, display images,
and panel settings (page 81).
Outputs a 2Vp-p, square signal for compensating the
probe (page 96) or demonstration.
Powers the oscilloscope on or off.
The saved display image is too dark on the background.
Use the Inksaver function which reverses the background color. For details, see page 35.
The accuracy does not match the specifi cations.
Make sure the device is powered on for at least 30 minutes, within +20°C~+30°C. This is necessary
to stabilize the unit to match the specifi cation.
The SD card slot does not accept my card.
Make sure is: 1. a standard SD card (MMC and SDHC is not supported), 2. 2GB or less, and 3.
formatted as FAT or FAT32.
The oscilloscope will not allow a 2M waveform to be saved.
Make sure that only 1 channel is active. Make sure that the signal has been triggered and that the
STOP or Single key has been pressed.
Ensure the time base is slower than 10 ns/div. See page 80.

Fuse socket
Power cord socket accepts the AC mains, 100 ~ 240V,
50/60Hz.
The fuse socket holds the AC main fuse, T1A/250V.
For the fuse replacement procedure, see page100.
The waveform does not update (frozen).
Press the Run/Stop key to unfreeze the waveform. See page 26 for details. For trigger setting details,
see page 70.
If this does not help, press the CH key. If the signal still does not appear, press the Autoset key.
The probe waveform is distorted.
You might need to compensate the probe. For details, see page 96.
Note that the frequency accuracy and duty factor are not specifi ed for probe compensation waveforms
and therefore it should not be used for other reference purposes.

Setting up the Oscilloscope
Background This section describes how to set up the oscilloscope properly including adjusting
the handle, connecting a signal, adjusting the scale, and compensating the
probe. Before operating the oscilloscope in a new environment, run these steps
to make sure the oscilloscope is functionally stable.
Procedure Pull both bases of the handle out 1.
slightly.
Procedure Connect the probe between Channel1 input and the probe compensation 1.
