Making a measurement Chapter 3
Visco 88 Page 3-5
Choosing a measurement system
Eight different systems (combinations) are available for the cup and bob and for the
cone and plate/parallel plate measuring systems. The tables in
Chapter 2 give the
main settings to use for each type of measuring system and these are summarised in
a single table below. For example, select
System 2 if planning to use the 25mm
inner cylinder and 27.5mm outer cylinder while using the default constant set, 1 .
The measuring system to use will depend on the sample. Once this is known, select
the appropriate System setting using the
SYSTEM switch. The number on the vis-
cometer’s display (between 1 and 8) indicates the system chosen.
Caution!
Take special care when handling measuring systems. Attach and remove
them carefully. Return them to the storage case when not in use.
Measuring system combinations
This table shows all the combinations of SYSTEM switch setting and constant set
(1 to 8) used for any measuring system setup. Details of how to change the constant
set are given in
Chapter 4 , though there should be no need to change from set 1 ,
the default, for cup and bob. For cone and plate/parallel plate measuring systems,
use set
5 .
