6.
Release the START button. The display will show which set of constants is
selected (
Se
t.n
where n is 1 to 8 ) for a couple of seconds and will then go into
normal measuring mode. For example, the second set would be displayed as
Se
t.
2
.

The set selection is stored while the instrument is powered off. The current set
is indicated by a small number from 1 to 8 at the bottom of the display.
Freezing the display
The last measured value can be 'frozen' by pressing the
CAL
button. To do this,
the motor must be running and the viscometer must be under front panel control
(not software control).
In
Freeze mode
the mode indicator flashes. Once the current measurement has
been frozen, the display can be stepped as usual with the
FUNCTION
button to
display any of the measuring points at the time when the
CAL
button was pressed.
To return to the normal display updates, press
CAL
again. (Freeze mode is also
terminated if any of the
SPEED
or
SYSTEM
selectors are changed or the motor is
stopped).
Note
Do not press CAL immediately after changing the speed (i.e. when the
LCD reads '----') as a few seconds are necessary for Freeze mode to
become active.
