CHAPTER1

Introduction to this manual

Access to the Accessory

Within this manual reference is made to the various people that will have access to

the Accessory. Below is a list of these people and their responsibility:

Malvern personnel

Malvern personnel (service engineers, representatives etc.) have full access

to the Accessory and are authorised to perform all service procedures that

may be required.

Supervisor

The supervisor is the person responsible for the management/safety of the

System and of its operation. The supervisor is responsible for the training

of the operators. The supervisor can perform all user maintenance routines

identified in chapter 9, including changing the fuses.

Operator

An operator is a person trained in the use of the system. The operator can

perform all user maintenance routines identified in chapter 9, except

changing the fuses.

Systems covered by this manual

This manual covers the installation, operation and maintenance for the QS Small

Volume Sample Dispersion Unit. This accessory is used in association with

various Mastersizer optical units.

Mastersizer is a generic name given to a family of systems. Each system within the

family uses the same principles of operation and only vary in operation in small

areas. For this reason the manual has been written to cover more than one

instrument.

CHAPTER 1

QS SMALL VOLUME SAMPLE DISPERSION UNIT

Page 1.1

This manual covers the Accessory in association with the following Mastersizer

family members:

Instrument. Ref. Number.

Mastersizer X standard bench. MAM 5000

Mastersizer X long bench. MAM 5002

Mastersizer S standard bench. MAM 5004

Mastersizer S long bench. MAM 5005

Mastersizer Micro. MAF 5000

Mastersizer Microplus. MAF 5001

Assumed information

For clarity this manual will assume that you are using your Accessory in

association with a standard bench Mastersizer S. If there are any operational

procedures that differ when in use with another Mastersizer family member, the

alternative information will be given.

Within this manual the QS Small Volume Sample Dispersion Unit will be

referred to as the “Small Volume Sample Dispersion Unit”, or as the “Accessory”.

Throughout this manual the Small Volume Sample Dispersion Unit refers to the

Dispersion Unit & the Controller Unit.

Within this manual the Mastersizer system will be referred to as the “Mastersizer”

or the “system” unless the information given is for a particular instrument.

Windows terms

It is important that you understand some windows terms before reading further.

Refer to chapter 1 of the Getting Started manual.

Menu Commands

Menu commands from the Malvern software are referred to in the form main

menu-menu item. As an example, the command Setup-Hardware refers to

selecting the Hardware item in the Setup menu. The same rules apply for

sub-menus of sub-menus. Menu commands are always shown in bold text.
