The current control variable is saved as the reference 100% ΔP
and shown on the digital display. The change in the viscosity is
then shown in %. Depending on whether the viscosity increases
or decreases, the percentage rises or falls above or below 100%
respectively.
• Scroll to the “Stirring” icon
in the menu
• Open the submenu by
pressing the rotary knob
(D)
• Open the “Torque trend
measurement” submenu
and confirm by pressing
the rotary knob (D)
• Acknowledge the informa-
tion screen displayed
Weighing module
The weighing module is a function which allows the user to
perform simple weighing
tasks.
• To start the weighing pro-
cess, press the (G) button
on the front membrane or
alternatively select Weig-
hing from the menu. Press
the rotary knob (D) to start
the weighing function.
Note:
The heating and stirring
functions must be deacti-
vated.
• It may take several
moments for the system to
stabilise.
Once the system is stable,
a “g” will be shown
alongside the measured
value.
Weighing - Calibration
• Open the “Calibration”
submenu and confirm by
pressing the rotary knob
(D)
• Enter the calibration
weight and confirm by
pressing the rotary knob
(D)
• Place the calibration
weight on the mounting
plate and wait until the
device indicates that the
calibration process has
been completed.
This process needs to be
repeated two or three
times before closing cali-
bration mode
Once the calibration
process has been
completed successfully, the
weighing module is ready
for use.
Regularly re-calibrate the
device.
Timer / Counter
The Timer function allows the user to stop the heating process
after a certain time has lapsed. The Timer function can be set for
up to 99 hours, 59 minutes and 59 seconds.
Note:
The time starts to count down when starting both functions
(heating and/or stirring).
Once the heating function is activated, the timer function only
refers to heating. The stirring function continues to operate as
previously, thereby avoiding a delay in boiling in the liquid. The
motor is only switched off when the heating function is not
active. The stirring function is stopped if the heating function is
not started during the timer cycle and the time runs out.
NOTE:
By entering a value of 00:00:00 (hh:mm:ss), the counter is
activated. The counter shows the time elapsed during the current
experiment.
