The first WARNING note below is
required by the FCC and relates only to the
interference potential of this equipment.
This message is a direct quotation.
WARNING
The equipment generates, uses, and can
radiate radio frequency energy and if
not installed and used in accordance
with the instructions manual, may
cause interference to radio
communications. As temporarily
permitted by regulation, it has not been
tested for compliance with the limits for
Class A computing devices pursuant to
Subpart B or Part 15 of FCC Rules,
which are designed to provide
reasonable protection against such
interference. Operation of this
equipment in a residential area is likely
to cause interference, in which case the
user at his own expense will be required
to take whatever measures may be
required to correct the interference.
The design of this instrument has been
verified to EN 61010 for Class 1 (grounded
use).
This manual contains information and
warnings that must be observed to keep the
instrument in a safe condition. The
instrument should not be switched on if it is
damaged and it should not be used under
wet conditions.
For the correct and safe use of this
instrument it is essential that both operating
and service personnel follow generally
accepted safety procedures in addition to
the safety precautions specified in this
manual.
Whenever it is likely that safety protection
has been impaired, the instrument must be
made inoperative and secured against any
unintended operation. Qualified
maintenance or repair personnel should be
informed. Safety protection is likely to be
impaired if, for example, the instrument
shows visible damage or fails to operate
normally.
This instrument must not be used in life
support roles.
GROUNDING
The instrument must be used with a
protective ground connected via the
conductor of the supply cable.
This is connected to the instrument before
the line and neutral connections when the
supply connection is made. If the final
connection to the supply is made elsewhere,
ensure that the ground connection is made
before line and neutral.
WARNING
Any interruption of the ground
connection inside or outside is likely to
make the instrument dangerous.
Intentional interruption is prohibited.
Signal connections to the instrument should
be connected after the ground is made and
disconnected before the ground connection
is removed, i.e. the supply lead must be
connected whenever signal leads are
connected.

Chapter 1: Safety Messages Ultima 500 DSO
1-4 Version 2.3
WARNING
It is recommended that signal grounds
always be connected to a local ground.
For safety, it is essential that a signal
earth be connected whenever voltages
greater than 40 V peak are connected.
This is to prevent the instrument’s case
becoming live in the event of a safety
ground interruption, which could occur
if the supply connector is accidentally
disconnected from the rear of the
instrument.
It is the responsibility of the user to ensure
the safety of any accessories, such as probes,
used with the instrument.
CAUTION
Even low voltage inputs may contain
high voltage fast transients (spikes),
which could damage the input. For this
reason it is not safe, for instance, to
make direct connections to an AC line
supply.
CAUTION
The outer shells of the input BNC’s are
connected to the oscilloscope’s chassis
and therefore to the safety ground.
Note: In order to verify the continued safety of
this equipment, it is necessary to routinely
check the earth bonding and insulation
resistance. This should be done by a
suitably qualified person.
LIVE PARTS
The covers protect the user from live parts
and should only be removed by suitably
qualified personnel for maintenance and
repair purposes.
The instrument must not be operated with
the covers removed.
There are no user serviceable parts inside.
ENVIRONMENT
The instrument should be operated in a
clean, dry environment with an ambient
temperature of between 0°C and +50°C.
The instrument is specified for use in a
Pollution Category II environment, which is
normally non-conductive with temporary
light condensation, but it must not be
operated while condensation is present. It
should not be used in more hostile, dusty or
wet conditions.
The instrument will operate with full,
specified accuracy between +15°C and
35°C.
Note: Direct sunlight, radiators and other heat
sources should be taken into account when
assessing the ambient temperature.
The instrument relies on forced air cooling
with fan and ventilation apertures. Adequate
ventilation can usually be achieved by
leaving a 75 mm (3" gap) around the
instrument. Care should be taken to avoid
restricting the airflow around the fan holes
at the side of the instrument.
To clean the DSO, disconnect all power
sources and wipe the surfaces lightly with a
clean, soft cloth dampened with water.
For the correct connection of accessories
and operation please turn to Chapter 8 of
this guide, Tutorial.

Ultima 500 DSO Chapter 1: Safety Messages
Version 2.3 1-5
POWER AND FREQUENCY
REQUIREMENTS
The instrument uses up to 250 W/ 350 VA
and operates from line voltages of 90 V to
260 V at 45-400 Hz to installation Category
II, local level supplies distributed within a
building. Under the extreme conditions of
90 V and 45 Hz, the instrument will still
operate correctly even if there is a half cycle
dropout in the line supply.
The power connection is via a standard
IEC, CEE 22 connector. Before connecting
the instrument to the supply ensure that the
rear panel AC supply voltage selector is set
to the appropriate voltage.
The AC supply fuse must be changed to suit
the supply voltage as shown in the table.
Access to the AC supply fuse can only be
made if the AC supply connector is
removed.
To disconnect the instrument from the AC
supply, unplug the IEC connector on the
rear of the instrument. The instrument
should be positioned to allow access to the
AC connector. The front power switch on
the instrument is not a disconnecting device.
When the instrument connected some
power will be consumed.
EMC
EMC stands for Electro-Magnetic
Compatibility. The overall intention is that
electronic equipment must be able to co-
exist with other electronic equipment in its
immediate vicinity and neither emit large
amounts of electromagnetic energy. Thus
there are two distinct requirements for
electromagnetic compatibility: Emission and
Immunity.
This instrument generates, accepts and can
radiate radio frequency energy and, if not
installed and used in accordance with the
operator manual, may cause harmful
interference to other equipment. However,
there is no guarantee that interference will
not occur in a particular installation.
Immunity test: All immunity tests are done
with the failure criterion being a change of
the instrument’s control settings. Any of
these tests may produce a spurious trigger.
Measurements are not valid during and
immediately after the immunity tests.
In demanding applications, if this
instrument does cause minor harmful
interference to other equipment, which can
be determined by turning this instrument
off and on, the user is encouraged to try to
reduce the interference by one or more of
the following measures:
•Re-orient or relocate the affected
equipment.
•Increase the separation between the
instrument and the affected equipment.
•Re-orient or relocate RS 423 and/or
IEEE-488 interface cables.
•Connect the instrument to an outlet on
a different supply circuit to the affected
equipment.
Supply cables, interface cables and probes
should be kept as short as practical,
preferably a maximum of 1 m interface
cables should be screened and interface
cables longer than 3 m are not acceptable in
terms of interference port immunity.
FUSE REQUIREMENTS
The fuse arrangement stated here must be
followed and, additionally, in the UK a fuse
should be fitted in the line supply plug.
The fuse must be slow blow (T) & High
Breaking Capacity (H). Fuse rating IEC
(UL/CSA) 5A (6A).

opening of covers for removal of parts
is likely to expose live parts.
Whenever it is likely that the protection has
been impaired, the apparatus shall be made
inoperative and be secured against any
unintended operation.
The protection is likely to be impaired if, for
example, the apparatus shows visible
damage or has been subjected to severe
transport stresses.

SÄKERHETSVARNING
Detta instrument måste drivas med en
skyddande jordledning ansluten via den
skyddande jordledaren på matarkabeln eller,
om instrumentet har sådan monterad, via
det jordade uttaget. Om jordanslutningen
störs, inuti eller utanför instrumentet, är det
troligt att instrumentet kommer att utgöra
en fara. Avsiktlig störning är förbjuden.
Dessutom måste en signaljord anslutas om
någon av ingångssignalerna överstiger 40 V
topp.
Tag ej bort skydden.
Om matarsäkringen smälter på grund av ett
fel är det möjligt att strömställaren för
växelströmsmatning på instrumentet skadas
och den bör då inspekteras av en ingenjör
med lämpliga kvalifikationer.
För att koppla bort instrumentet från
växelströmstillförseln, tag ut IEC-
anslutningen på bakpanelen. Strömställaren
för växelströmstillförsel på detta instrument
är enbart till för funktionerliga ändamål.
Den är inte avsedd som, eller lämplig som,
en bortkopplingsanordning.
