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 DSO­1000D.
5
DSO-1000D 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 DSO-
1000D.
Avoid severe impact or rough handling that
leads to damaging the DSO-1000D.
Do not discharge static electricity to the DSO-
1000D.
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 DSO-1000D unless you
are qualified.
(Measurement categories) EN 61010-1:2010 specifies the measurement categories and their requirements as follows. The DSO-1000D 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, 50 - 60Hz,
auto selection. Power consumption: 30 Watts.
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid electrical shock.
Cleaning the DSO-1000D
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 61010-1:2010 specifies the pollution degrees and their requirements as follows. The DSO-1000D 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.

Location: Indoor Temperature: -10ºC to 60ºC Humidity: Up to 93% RH (non-condensing) /
≤40ºC, up to 65% RH (non-condensing) / 41ºC ~ 60 ºC
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

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.

The acquisition mode determines how the samples are used to reconstruct a waveform.
Sample
This is the default acquisition mode. Every sample from each acquisition is used.
Peak detect
Only the minimum and maximum value pairs for each acquisition interval (bucket) are used. This mode is useful for catching abnormal glitches in the signal.
Average
Multiple acquired data is averaged. This mode is useful for drawing a noise-free waveform. To select the average number, use the Variable knob.
Average number: 2, 4, 8, 16, 32, 64, 128, 256
Panel Operation
1. Press the Acquire key.

The XY mode maps the input of channel 1 to the input of channel 2. In 4 channel models, the input of channel 3 can be mapped to the input of channel
4. This mode is useful for observing the phase relationship between waveforms.
Reference waveforms can also be used in XY mode. Ref1 is mapped to Ref2 and Ref3 is mapped to Ref4. Using the reference waveforms is the same as using the channel input waveforms.
Connection
1. Connect the signals to
Channel 1 (X-axis) and Channel 2 (Y-axis) or Channel 3 (X2-axis) and Channel 4 (Y2-axis).

XY mode is split into two windows. The top window shows the signals over the full time range. The bottom window shows XY mode.
To move the X Y waveform position, use the vertical position knob: Channel 1 knob moves the X Y waveform horizontally, Channel 2 knob moves the X Y waveform vertically. Similarly, the X2 and Y2 axis can be positioned using the channel 3 and channel 4 vertical position knobs.
