Safety Symbols

These safety symbols may appear in this manual or on the instrument.

GDS-200 & GDS-300 Series User Manual

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.

Safety Guidelines

SAFETY INSTRUCTIONS

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.

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:

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.

GETTING STARTED

Background

Unlike other oscilloscopes or digital multimeters, the GDS-200 and GDS-300 Series have no physical hardware keys, therefore operation is completely controlled using the capacitive touch screen. Using a capacitive touch screen is a new interface paradigm for DSOs; the gestures and general user interface is easier to use and more intuitive than traditional DSO interfaces. Before you begin to use these instruments, we highly recommend you take a few moments to get to know the basic gestures and interface conventions.

Basic Gestures

There are a few basic gestures that can be used to operate the GDS-200/GDS-300. When asked to perform a gesture throughout the user manual, you can refer to the gestures below.

Tap / Press

Tap/Press once to select an item.

The gesture will be recognized after you lift your finger off the display.

Long Press / Tap & Hold

Tap & hold

Press and hold an item until a submenu system or secondary option appears.
