Safety Notes

Product Intention

PowerLab systems have been designed only for use in teaching and

research applications. They are not intended for clinical or critical life-

care use and should never be used for these purposes, nor for the

prevention, diagnosis, curing, treatment, or alleviation of disease,

injury, or handicap.

Applicable Safety Standards

When used with insulated transducers or ADInstruments isolated

front-ends, PowerLab systems are safe for human connection. The

ML132 Bio Amp, ML135 Dual Bio Amp, ML408 Dual Bio

Amp/Stimulator, ML116 GSR Amp, ML117 BP Amp and ML180 front-

ends conform to international safety requirements. Speciﬁcally, these

requirements are IEC601-1 and its addenda (Table S–1), and various

harmonised standards worldwide (UL2601.1 in the USA, and

AS/NZS3200.1 in Australia and New Zealand). In accordance with

European standards they also comply with the electromagnetic

compatibility requirements under EN60601-1, which encompasses the

EMC directive. Further information is available on request.

PowerLab Owner’s Guide

General Safety Instructions

• Since the PowerLab is used in conjunction with a computer

(which has much higher leakage currents) the subject must be at

least 1.83 metres (6 feet) away from any of the equipment, to

avoid contact with the computer. The Bio Amp or BP Amp cable

provides enough distance. Alternatively, an isolation transformer

can be used to supply power to both the PowerLab and the

computer.

• The PowerLab /4

, PowerLab /8

and PowerLab /16

should

always be ﬁtted with the recommended fuses for safe operation.

Speciﬁc information on fuse types and replacement is given in a

later chapter.

• The PowerLab /4

, PowerLab /8

and PowerLab /16

are

classiﬁed as Class I medical equipment, which means that

protection against electric shock in the event of a fault relies on a

direct connection through the power cable to your building’s

earth conductor. The power cable supplied with your PowerLab

provides the required ground connection to the power outlet. If

your building does not have power outlet sockets with a good

ground connection, then you may use the ground connection on

the rear of the PowerLab to provide the equipotential connection

to the building’s earth conductor. A ground connection is an

essential part of this equipment’s safety. Never use the PowerLab

without a ground connection.

Safety Symbol Explanation

Every ADInstruments device designed for connection to humans,

including the Bio Amp, BP Amp, GSR Amp and Stimulus Isolator,

carries one or more of three safety symbols, as shown in Figure S–1.

These symbols appear next to those input and output connectors that

can be directly connected to human subjects.

Safety Notes vii

The three symbols are:

•

BF (body protected) symbol

. This means that the input

connectors are suitable for connection to humans provided there is

no direct electrical connection to the heart.

•

Warning symbol

. The exclamation mark inside a triangle means

that you should consult the supplied documentation (you’re

reading it) for operating information or cautionary and safety

information before using the device.

•

CF (cardiac protected) symbol

. (Appears on some models of Bio

Amp, and every BP Amp.) This means that the input connectors

are suitable for connection to humans even when there is direct

electrical connection to the heart.

Cleaning and Sterilisation

This system is not supplied with materials or components likely to

need sterilisation. If you need to clean peripherals likely to be in

contact with different subjects, they can be cold-sterilised with an

appropriate sterilising agent. No part of the system can be autoclaved.

Storage

It is recommended that the hardware be kept below 40

C and above

C in a moisture-free or low-humidity environment when not in use

(storage only). Electronic components are susceptible to corrosive

substances and atmospheres, so it is also advisable to keep the system

away from laboratory chemicals.

protected equipment

PowerLab Owner’s Guide

Preventative Inspection and Maintenance

Both PowerLab systems and ADInstruments front-ends are

maintenance free and do not require periodic calibration or

adjustment to ensure medical safety. Internal diagnostic software

performs system checks during power up and will report errors if a

signiﬁcant problem is found.

There is no need to open the instrument for inspection or

maintenance, and doing so within the warranty period will void the

warranty.

If you so wish, your PowerLab system can be periodically checked for

basic medical safety by using an appropriate medical safety testing

device. Tests such as earth leakage, earth bond, insulation resistance,

patient leakage and auxiliary currents and power cable integrity can

all be performed on the PowerLab system without having to remove

the covers. You should follow the instructions for the testing device if

performing such tests.

If the PowerLab system is found not to comply with such testing you

should contact your PowerLab dealer to arrange for the equipment to

be checked and serviced. You should not attempt to service the device

yourself.

CHAPTER ONE

Overview

Your PowerLab recording unit, together with a range of specialised

application programs, provides a versatile data recording and

analysis system when used with a Windows or Macintosh computer.

This chapter provides an overview of the PowerLab system and

describes the basic features, connectors, and indicators of the SP

series PowerLabs: the PowerLab/4

, PowerLab/8

, and

PowerLab/16

PowerLab Owner’s Guide

How to Use this Guide

This owner’s guide describes how to set up and begin using your

PowerLab recording unit. The chapters provide an overview of the

PowerLab system (the combined software and hardware package),

and a more detailed look at the features of your recording unit and its

connection to your computer. The appendixes provide technical

information about the recording unit, and solutions to problems. At

the end of this guide is a glossary of hardware terms, an index, and

warranty information.

The speciﬁcations and diagrams included in the appendixes are there

to help the more technically minded to understand what the

PowerLab can and cannot do, but this is not a service manual: only an

authorised ADInstruments distributor should attempt repairs. If you

modify the recording unit yourself, you void any rights you have

under warranty.

The user’s guides for the Chart and Scope application programs

provide detailed information on the software side of the PowerLab

system and its uses in acquiring, storing, and analysing data. Read

them after you have connected the PowerLab to your computer.

First, Check Your PowerLab!

Please do not attempt to connect the PowerLab to a power outlet or

computer or turn it on until you have read the ﬁrst two chapters of

this owner’s guide, and have checked it as described below.

1. Check that all items in the accompanying packing list are

included in the box.

2. Check that there are no obvious signs of external damage to the

PowerLab.

3. Check that there are no obvious signs of internal damage, such as

rattling. Pick the PowerLab up, tilt it gently from side to side, and

listen for anything that appears to be loose.

4. Check that the correct voltage for your country is shown on the

back of the unit. Your PowerLab should be delivered with the
