SAFETY INSTRUCTIONS
This chapter contains important safety instructions that should be followed when operating
and storing the function generator. Read the following before any operation to ensure your
safety and to keep the function generator in the best condition.
Safety Symbols
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 function generator or to other objects or property.
DANGER High Voltage
Attention: Refer to the Manual
Protective Conductor Terminal
Earth (Ground) Terminal
DANGER Hot Surface
Double Insulated

SAFETY INSTRUCTIONS
22/11/2016 Version No. 002 5
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 heavy objects on the instrument.
Do not place flammable objects on the instrument.
Avoid severe impact or rough handling that may damage the
function generator.
Avoid discharges of static electricity on or near the function
generator.
Use only mating connectors, not bare wires, for the terminals.
The instrument should only be disassembled by a qualified
technician.

AFG-31000 Series Instruction Manual/English
6 22/11/2016 Version No. 002
(Measurement categories) EN 61010-1:2001 specifies the
measurement categories and their requirements as follows. The AFG-
31000 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 ~ 240VAC, 50 ~ 60Hz.
Connect the protective grounding conductor of the AC power cord
to an earth ground to prevent electric shock.
Fuse
WARNING
Fuse type: T1A/250V.
Only qualified technicians should replace the fuse.
To ensure fire protection, replace the fuse only with the specified
type and rating.
Disconnect the power cord and all test leads before replacing the
fuse.
Make sure the cause of fuse blowout is fixed before replacing the
fuse.

SAFETY INSTRUCTIONS
22/11/2016 Version No. 002 7
Cleaning the function
generator
Disconnect the power cord before cleaning the function generator.
Use a soft cloth dampened in a solution of mild detergent and
water. Do not spray any liquid into the function generator.
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) and avoid strong magnetic
fields.
Relative Humidity: < 80%
Altitude: < 2000m
Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2001 specifies pollution degrees and their
requirements as follows. The function generator 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.

AFG-31000 Series Instruction Manual/English

Storage environment
Location: Indoor
Relative Humidity: < 70%
Temperature: -10°C to 70°C
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.
Power cord for the United Kingdom

SAFETY INSTRUCTIONS
22/11/2016 Version No. 002 9
When using the function generator 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 3Aor 5A fuse. Larger conductors would
normally require 13A types, depending on the connection method used.

AFG-31000 Series Instruction Manual/English
10 22/11/2016 Version No. 002
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.
