SAFETY INSTRUCTION
This chapter contains important safety instructions
that should be followed when operating and
storing the oscilloscope. Read the following before
any operation to ensure your safety and to keep
best condition for the oscilloscope.
Safety Symbols
These safety symbols may appear in this manual or on the
oscilloscope.

Fuse
WARNING
• Fuse type: T1A/250V
• To ensure fire protection, replace the fuse only
with the specified type and rating.
• Disconnect the power cord before replacing the
fuse.
• Make sure the cause of fuse blowout is fixed
before replacing the fuse.
Cleaning the
oscilloscope
• Disconnect the power cord before cleaning the
oscilloscope.
• Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into the oscilloscope.
• Do not use chemical 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)
• Relative Humidity: < 80%
• Altitude: < 2000m
• Temperature: 0°C to 50°C
(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees
and their requirements as follows. the oscilloscope falls un der
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: No rmally only non-conduc tive p ol lu tion
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 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:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wire s in main leads may not correspond with the
colours 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 the letter E or by the earth symbol
or 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 instr uctions provided with the equipment or contac t
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, 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 moulded mains connector that requires removal /replacement must be
destroyed by removal of any fuse & fuse carrier and disposed of immediately,
as a plug with bared wir es is hazardous if a engaged in live socket. Any rewiring must be carried out in accordance with the information detailed on
this label.

CONFIGURATION
The Configuration chapter describes how to
configure panel settings to make measurements
and observations suited to the application needs.
Acquisition
The acquisition process samples the analog input signals and
converts them into digital format for internal processing. You may
select the normal, average, or peak detect acquisition mode.

sampling
The oscilloscope automatically switches between
two sampling modes, Real-time and Equivalent-
time, according to the number of active channels
and sampling rate.
One sampled data is used to reconstruct a single
waveform. Short-time events might get lost if the
sampling rate gets too high. This mode is used
when the sampling rate is relatively low
(250MSa/s or lower).
Multiple numbers of sampled data are
accumulated to reconstruct a single waveform.
Restores greater waveform details but takes longer
to update the waveform. This mode is used when
the sampling rate becomes higher than 250MSa/s.
The maximum equivalent-time sampling rate is
25GSa/s.

the procedure.
9. The calibration is completed and the display
goes back to the previous state.
Probe Compensation
Procedure
1. Connect the probe between Channel1 input and
the probe compensation output (2Vp-p, 1kHz
square wave) on the front panel. Set the probe
attenuation to x10.

FAQ
•
The input signal does not appear in the display.
•
I want to remove some contents from the display.
•
The waveform does not update (frozen).
•
The probe waveform is distorted.
•
Autoset does not catch the signal well.
•
I want to clean up the cluttered panel settings.
•
The accuracy does not match the specifications.
•
The SD card slot does not accept my card.
Note that the frequency accuracy and duty factor are not specified
for probe compensation waveform and therefore it should not be
used for other reference purpose.
Autoset does not catch the signal well.
Autoset function cannot catch signals under 30mV or 30Hz. Please
use the manual operation. See page35 for details.
I want to clean up the cluttered panel settings.
Recall the default settings by pressing the Save/Recall key→Default
Setting. For default setting contents, see page32.
DSO-4000 User Manual
The input signal does not appear in the display.
Make sure you have activated the channel. If not, press the CH key.
If the signal still does not appear, press the Autoset key.
I want to remove some contents from the display.
To clear the math result, press the Math key twice (page46).
To clear the cursor, press the Cursor key again (page44).
To clear the Help contents, press the Help key again (page33).
The waveform does not update (frozen).
Press the Run/Stop key to unfreeze the waveform. See page36 for
details. For trigger setting details, see page61.

The saved display image is too dark on the background.
Use the Inksaver function which reverses the background color. For
details, see page81.
The accuracy does not match the specifications.
Make sure the device is powered on for at least 30 minutes, within
+20°C~+30°C. This is necessary to stabilize the unit to match the
specification.
The SD card slot does not accept my card.
Make sure it is a 1. Standard SD card (MMC and SDHC are not
supported), 2. 2GB or less, and 3. FAT or FAT32 formatted.
For more information, please contact your local dealer.
