FOR UNITED KINGDOM ONLY

NOTE: This lead / appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are colour-coded 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 the letter E or by the earth symbol or coloured Green 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 a competent electrician or contact RS Components for further advice.

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 or replacement must be destroyed by removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires is hazardous if engaged in live socket. Any re-wiring must be carried out in accordance with the information detailed on the wiring label, this Instruction Book and comply with current wiring regulations.

IDS-706/710/720/806/810/820 Operation Manual

The IDS-706, 710, 720, 806, 810 & 820 advanced 32-bit microprocessor controlled Digital Storage Oscilloscopes have been designed for a wide range of applications in educational, service and industrial applications. The instruments offer a combinations of trigger control, frequency response, time base versatility and other functions to facilitate measurements and observations, which are generally only available on more expensive oscilloscopes. For ease of operation an “Autoset” function allows for signal related automatic setup of measuring parameters. On-screen readouts and cursor functions for voltage, frequency and frequency related measurement provide extraordinary operational convenience. Fifteen different user defined instrument settings can be saved and recalled without restriction. The built-in RS-232 serial interface allows for remote controlled operation by a PC. A six-digit frequency counter provides extra functionality. The standard USB port permits the “dump” of the entire contents of the instruments’ LCD screen to computer via specific software. A “Program” mode is provided to record all the necessary waveform measuring operations and replay all steps as required. The additional “Go, No-Go” function allows for a simple semi-automated comparison of waveforms with predetermined limits.

3. First Time Operation

The following text assumes that the “SAFETY” section of this manual has been read carefully and understood.

Each time before the instrument is put into operation, check that the oscilloscope is connected to protective earth. For this reason the power cable must be connected to the oscilloscope and the power outlet first. Next, connect the test lead(s) to the oscilloscope input(s). Check that the equipment or unit under test is switched off and connect the test lead(s) to the test point(s). Lastly, switch on the instrument and afterward the equipment or device under test.

The oscilloscope is switched on by a single press of the ON/STBY button (Before depressing the ON/STBY button on the front panel, ensure the main power switch on the rear panel is switched on). After a few seconds the oscilloscope will initialize and revert to its last used operating mode.

Tilt-stand: For desktop use, lock the tilt-stand in place as shown in the following diagrams:

Probe calibration

To display an undistorted waveform on an oscilloscope, the probe must be matched to the individual input impedance of each vertical amplifier.

For this purpose a square wave signal with a very fast rise time and minimum overshoot should be used, as the sinusoidal contents cover a wide frequency range.

The build-in compensation signal generator provides a square wave signal with a very fast rise time, and frequency of approx. 1kHz from the output socket below the LCD screen. As the square wave signals are used for probe compensation adjustment, neither the frequency accuracy nor the pulse duty factor are of importance and therefore not specified.

The output provides 2Vpp±3% for a 10:1 probe. When the Y deflection coefficient is set to 50mV/div, the calibration voltage corresponds to a vertical display of 4 divisions (10:1 probe). Connect the probe to the probe calibration output and check the waveform indicates correct compensation (see Figure 3-2). If the waveform indicates over or under compensation, refer to the instructions for the probe and adjust the compensation.
