General	•	Make sure the BNC input voltage does not exceed 300V peak.
Guideline
	• 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 heavy objects on the oscilloscope.
	• Avoid severe impact or rough handling that may damage the oscilloscope.
	• Avoid discharges of static electricity on or near the oscilloscope.
	• Use only mating connectors, not bare wires, for the terminals.
	• Do not block the cooling fan vent.
	• Do not perform measurements at power sources and building installation sites
		(Note below).
	• The oscilloscope should only be disassembled by a qualified technician.
	(Measurement categories) EN 61010-1:2001 specifies the measurement categories
	and their requirements as follows. The GDS-1000A 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 • AC Input voltage: 100 ~ 240V AC, 47 ~ 63Hz

•The power supply voltage should not fluctuate more than 10%.

Fuse	•	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	•	Disconnect the power cord before cleaning the oscilloscope.
oscillo-scope	•	Use a soft cloth dampened in a solution of mild detergent and water. Do not
		spray any liquid into the oscilloscope.
	• Do not use chemicals containing harsh products such as benzene, toluene,
		xylene, and acetone.
Operation	•	Location: Indoor, no direct sunlight, dust free, almost non-conductive pollution
Environment		(Note below)
	• Relative Humidity: < 80%
	•	Altitude: < 2000m
	• Temperature: 0°C to 50°C
	(Pollution Degree) EN 61010-1:2001 specifies pollution degrees and their
	requirements as follows. The oscilloscope 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, nonconductive 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 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.

Autoset does not catch the signal well.

The Autoset function cannot catch signals under 30mV or 30Hz.

Please operate the oscilloscope manually. See page 76 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 page 36.

The saved display image is too dark on the background.

Use the Inksaver function which reverses the background color. For details, see page 35.

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 is: 1. a standard SD card (MMC and SDHC is not supported), 2. 2GB or less, and 3. formatted as FAT or FAT32.

The oscilloscope will not allow a 2M waveform to be saved.

Make sure that only 1 channel is active. Make sure that the signal has been triggered and that the STOP or Single key has been pressed.

Ensure the time base is slower than 10 ns/div. See page 80.

The waveform does not update (frozen).

Press the Run/Stop key to unfreeze the waveform. See page 26 for details. For trigger setting details, see page 70.

If this does not help, press the CH key. If the signal still does not appear, press the Autoset key.

The probe waveform is distorted.

You might need to compensate the probe. For details, see page 96.

Note that the frequency accuracy and duty factor are not specified for probe compensation waveforms and therefore it should not be used for other reference purposes.
