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 GDS­2000A.

GDS-2000A 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-
2000A.
Avoid severe impact or rough handling that
leads to damaging the GDS-2000A.
Do not discharge static electricity to the GDS-
2000A.
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-2000A unless you
are qualified.
(Measurement categories) EN 61010-1:2010 specifies the measurement categories and their requirements as follows. The GDS-2000A 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, 48 ~ 63Hz,
auto selection. Power consumption: 96VA.
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid electrical shock.
Cleaning the GDS-2000A
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 61010-1:2001 specifies the pollution degrees and their requirements as follows. The GDS-2000A 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.
Storage environment
Location: Indoor
Temperature: -10°C to 60°C

Live (Phase)
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.

Demo and Probe Compensation Outputs
Demo
The Demo outputs are multifunction outputs that can be configured for probe compensation, as a trigger output or as a basic waveform generator for demonstration purposes. (FM signal, UART, I2C, SPI).
By default, the 3 Demo outputs are configured as:
1: Trigger output 2: FM waveform 3: Probe Compensation signal
CAL (Demo 3) outputs a 2Vp-p, square wave signal for probe compensation.
Please see page 171 for details.
