These safety symbols may appear in this manual or on the
instrument.
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 instrument or to
other properties.
DANGER High Voltage
Attention Refer to the 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.

Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the
instrument.
Avoid severe impact or rough handling that
leads to damaging the instrument.
Do not discharge static electricity to the
instrument.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the instrument unless you
are qualified.
Do not use sharp objects or press with undue
force on the touch screen display.
Do not apply more than 300Vrms (CAT II, DSO
inputs); 600V (CAT II, DMM inputs) or 300V
(CAT III, DMM inputs).
(Measurement categories) EN61010-1:2010, EN61010-2-030 and
EN61010-2-033 specify the measurement categories and their
requirements as follows. The GDS-200/300 falls under category II &
III.
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 0 is for measurements performed on
circuits not directly connected to Mains.

AC Adapter
Power Supply
(AC Mains)
WARNING
AC Input voltage range: 100VAC-240VAC
Frequency: 47Hz-63Hz
Output: 12 DCV, 36W Max
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Power Supply
(DC)
DC Input voltage range (10.5-13.5 V DC, 3A)
Cleaning the
Instrument
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 material
such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Relative Humidity: 20%- 85%
Altitude: < 2000m
Temperature: 0°C to 50°C
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The instrument 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.

Location: Indoor
Temperature: -25°C to 70°C
Relative Humidity: <90%
Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.
Battery
Type: Rechargeable Li-ion polymer
Model: FT8862103P
Manufacturer: Chinese Precision Technology
(Assembled in China)
Rating: 7.4Vdc ⎓, 6100mAh (45 Watt)
Battery Caution
The internal battery should not be replaced by
the end-user. Please return the unit back to your
local dealer for assistance.
Never allow the battery to come in contact with
fire or water.
Discard used batteries according to the
manufacturer’s instructions or local laws.
Read the manual before use.

Power cord for the United Kingdom
When using the instrument 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 0.75mm2should 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.

GETTING STARTED
This chapter will allow you to quickly set up a
GDS-200 or GDS-300 series oscilloscope and run
over the basic operation and features.
Before you can get started, you will need to check
the package contents (standard accessories, page
14). After the contents are checked the Overview
section will describe all the major features and
functions of the oscilloscopes in the GDS-200 and
GDS-300 series. The Appearance section will go
over the front, rear and side panels of the
instrument. The Display Overview will give a
brief introduction to the display and how the
display changes depending on the current
function, orientation or mode. Lastly the Getting
Started section will explain how to turn on the
instrument, explain how to set up the instrument,
and go over the gestures and operating
conventions that are used with the capacitive
touch panel on the unit.
