Shaking speed
The shaking speed, respectively Speed, turning knob (Fig. 5 no. 10) controls the speed of the shaking plate.
Depending on the rack used or the full gross weight (shaking plate, rack and sample vials / tubes), the shaking
plate will begin to move at a value of approx. 3.00 up to 4.50.
At the maximum possible setting of 10.00, the shaking plate will rotate at 1000 rpm. Please note
that the setting at the analogue turning knob does not correspond with the actual speed with
different adjustment values, i.e. with a setting of 8.00, for example, the shaking plate will not
rotate at 800 rpm, but only approx. 700 rpm depending on the gross weight.

Jumo® temperature controller
On the Jumo® temperature controller (Fig. 5 no. 7 and Fig. 19), the actual temperature can be read on the display
(Fig.10 no. 6). Additional menu items are also enabled on the Jumo® temperature controller for this purpose,
such as the operating hour display, the low/high temperature alarm, the alarm delay and the temperature offset
value.

Target temperature
To set the target temperature, press the “P” button. The display will alternate between the “SP” value and the
current target temperature. To change these, press the corresponding arrow button (Fig. 10 no. 4 or no. 5). Briefly
pressing the arrow button will change the value in 0.1°C increments. Continuously pressing the arrow button will
change the target temperature more quickly. If the desired target temperature value has been reached, you can
wait until the temperature controller changes back to its normal display or press the “P” button six times.
If the lid is open, the IR lamp heating will not heat up or illuminate; this is due to safety reasons.
If the heater switch (Fig. 5 no. 6) is switched off or in the “0” position, the IR lamp heating will also
not heat up or illuminate
If the temperature sensor is defective, the IR lamp heating will not heat up and the display (Fig.
10 no. 6) will alternate between “Err” and “¯ ¯ ¯“.
When removing individual samples or the rack, please note that the vacuum chamber wall,
temperature sensor and rack may pose risks of burns.
During the evaporation of volatile solvents, work with a low target temperature. If the target
temperature is too high, the mixture of gas and air may ignite. Please consult the data sheet of
the pertinent solvent for advice.
3.0.6.2
Operating hour display
Press the “P” button twice to read the operating hour display. The value “t. h” will appear alternately in the displa
y
and the current operating hours of the IR lamp heater in the lid respectively the compartment heater will be
displayed in hours (“xxh”). This value is merely informative and cannot be changed.
