This is a portable, easily-handled viscometer for laboratory, plant and field use. It can be used standalone or connected to a computer running the Bohlin software.The aims of this manual are to: Explain what the Visco 88 is and how it works. Describe the main hardware components. Explain how to use the instrument to make a measurement. Explain how to perform other tasks, for example adjusting the residual torque. Explain how to use the instrument connected to a computer running the Boh-lin software. Identify the user maintenance and troubleshooting procedures.How to use this manualWe recommend reading this manual fully before starting the first measurement. Users must read the Health and Safety information in Appendix A before operating the Visco 88. Appendix B gives the specification of the instrument.Access to the instrumentThis guide is for operators of the instrument. An operator is a person trained in the use of the system. The operator can perform all user maintenance routines identi-fied in Chapter 6. Chapter 1 Introduction to this manualPage 1-2 MAN 03781 NoteRemoval of the covers by anyone but a Malvern Instruments engineer will invalidate the warranty of the instrument. Where to get helpHelp deskAll queries regarding the system should initially be directed to the local Malvern Instruments representative. Please quote the following information: The model and serial number of the instrument (located with the connectors under the flap on the back of the casing). If the Bohlin software is being used with a computer connected to the instru-ment, the software version (to find this, select Help-About in the software).Contact the United Kingdom help desk if the local Malvern Instruments repre-sentative is not available. Its direct line is +44 (0) 1684 891800.NoteThis help line is primarily English speaking.Remote supportMalvern Instruments offers a remote support service, delivered by an Internet con-nection. Benefits include fast and efficient fault diagnosis, reducing downtime and costs. Online user training is also available, plus software updates. A high speed Internet connection is recommended for making use of this facility.Malvern website - www.malvern.comThe Malvern Instruments website offers a comprehensive range of material charac-terisation resources for use by customers 24 hours a day, seven days a week.Resources include Frequently Asked Questions, a knowledge base and application notes, plus information on other material characterisation solutions that Malvern can provide.iiVisco 88 Page 2-1 2What is the Visco 88?IntroductionThe Visco 88 is a portable, easily-handled viscometer for laboratory, plant and field use. Because of its wide selection of measuring systems, the Visco 88 is extremely suitable for demanding product and process control situations where precision is required.In addition to standalone use, the Visco 88 can be controlled by a connected com-puter. The computer can run the Bohlin software which allows pre-programmed measurements, as well as data processing and graphic layout of results. Use of this software is described in Chapter 5.This chapter describes: Operating principles. Key components. Measuring systems the cup and bob (the default) and cone and plate/parallel plate options. Temperature control. Connections. Power supply and battery operation.Chapter 2 What is the Visco 88?Page 2-2 MAN 03782 Operating principlesThe viscometer is a constant speed motor with a torque detection system. The sample to be tested is placed in the gap between upper and lower measuring sys-tems.The instrument uses a controlled shear
