Timer function
Time: This setting allows the user to specify the actual time for
the measurement procedure in the manual mode. A default time

tically after expiry of the set time, and the set time used for the
measurement procedure appears on the display.
Interval mode
The rotation can be run in an interval mode of alternating the
rotation direction.
Interval: The interval sets the time how long the rotation takes
place in one direction.
Activate: This entry activates the interval mode for the rotation.
Speed limit
The “Speed limit” menu allows the user to set the desired maxi-
mum and minimum speed limit for the rotation.
Note: The user can stop the measurement procedure before ex-
piry of the set time. In this case the countdown of the timer is
interrupted.

off the sound that occurs when the timer reaches 00:00:00. A tick

It is possible to define actions when the measurement is stopped
(manually or automatically).

perature will be from 20 °C to 90 °C. If oil is the medium, please

power value of a measurement. This value serves as information
and cannot be changed.
