SAFETY INSTRUCTIONS

This section contains the basic safety symbols that may
appear on the accompanying user manual CD or on the
instrument. For detailed safety instructions and
precautions, please see the Safety Instructions chapter
in the user manual CD.

Safety Symbols

These safety symbols may appear in the user 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

Protective Conductor Terminal

Earth (ground) Terminal

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.

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

0.75mm

2

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.

Setting up the Oscilloscope

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.

1. Pull both bases of the handle out slightly.
