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 SymbolsThese safety symbols may appear in the user manual or on the instrument.
Power Cord for the United KingdomWhen 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:
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.

Setting up the Oscilloscope
This section describes how to set up the oscilloscope properly including setting the stand, installing the optional modules and compensating the probe.
Tilting the Stand
The GDS-1000B has two adjustable tabs at the front that can be used to position the instrument into two preset orientations.
- Pull the tabs out to lean the scope back.
- Push the tabs under the casing to stand upright.
Probe Compensation
This section describes how to connect a signal, adjust the scale, and compensate the probe. Before operating the GDS-1000B in a new environment, run these steps to make sure the instrument performs at its full potential.
- Press the key to reset the system to the factory settings.
- Connect the probe to the Channel 1 input and to the probe calibration output. This output provides a 2Vp-p, 1kHz square wave for signal compensation by default.
- Set the probe attenuation voltage to x10.
- Press the autoset key.
- A square waveform will appear in the center of the display.
- Press the display key and select the Vector
- Turn the adjustment point on the probe to flatten the square waveform edge.
- Setting up the oscilloscope is complete. You may start to use the oscilloscope.
