cardiac pacemaker if you get too close.
Personnel with a cardiac pacemaker, implanted debrillator or dosing
pump should keep a minimum distance of 10 cm (4 inches) to the
device.
Warning:
Risk of slipping device!
As a result of vibrations generated during operation the device might
slide off the table top.
The surface must be smooth, clean and temperature resistant and
should be properly leveled.
➜Locate the stirring hotplate on a stable, horizontal surface.
➜Clean surface and feet with a damp cloth and ethanol regularly.

Operation
Place vessels
Caution:
Risk of breakage and spillage
If the stirring bars start rotation suddenly at high speed or the vessels
are not placed securely vessels might break or they may slip off and
spill the sample.
Prior to start heating and mixing ensure that all vessels are placed
with sample and stirring bars and that they are securely placed.
Heating bath accessories for round  asks and beakers as well as attachments for water,
gas and evaporating distributors are available.
➜To place a number of vessels securely on plate use optional adaptors (see general
catalogue).
➜Single vessels with  at bottoms like beakers may be placed directly on hotplate.
A single  ask should be arranged in the middle of the hotplate.
Several  asks should be distributed equally on the plate.

Operation
14
Mixing
When using device inside heating cabinets, make reference to
ambient conditions as stipulated in chapter “Technical data”.
Set speed and start rotation
Warning:
Risk of poisoning!
Open vessels and too high speed may result in samples splashing.
Use vessels with narrow neck especially if sample is dangerous or
toxic.
Adjust speed step by step until you have reached the required rpm
settings.
Wear safety glasses and especially with dangerous and toxic samples
appropriate protective clothing.
Speed can be set between 100 rpm - 1,400 rpm.

Heating
Set temperature
Warning:
Risk of burning!
The hotplate can reach temperatures up to 300 °C.
If you work with temperatures above 50 °C wear safety gloves and
appropriate protective clothing.
Warning:
Risk of ignition!
In ammable samples may ignite with high temperatures.
If you work with in ammable samples set temperature at least
25 °C lower than ignition point of sample.
There are two options to control heating:
▪Without external temperature sensor: temperature will be measured and controlled
via hotplate.
▪With external temperature sensor: temperature will be measured and controlled via
sensor directly in sample (see chapter “Assembly, Temperature sensor”).
You can set the following temperature range:
▪Hotplate / temperature sensor: between 20 °C and 300 °C (lower degrees depending
on ambient temperature).
Working without external temperature sensor:
Due to differences in heat conductivity of various materials of vessels
and sample the temperature of hotplate should be set 1½ to 4 times
higher than the desired sample temperature.

External temperature sensor Pt 1000
(optional accessory, see chapter “Accessories and spare parts”)
As soon as the external temperature sensor Pt 1000 is connected, temperature will not
be measured and controlled at hotplate but directly at sensor. (Connection see chapter
“Assembly, Connect temperature sensor Pt 1000”).
For reliable measurement the temperature sensor has to be inserted
at least 20 mm into sample.
Warning:
Risk of burning! Possible damage of device
If temperature sensor is not inserted in sample the sensor measures
and controls ambient temperature. The hotplate keeps up raising
temperature till max. temperature of 300 °C but set temperature can
never be reached.
If temperature sensor Pt 1000 is connected always insert sensor in
sample before heating is started.
Heating with external temperature sensor:
Carousel Tech, Carousel Connect
When external temperature sensor is connected, 2 additional functions are available:
▪Heating up “Fast” or “Precise”:
Fast mode: speeds up heating to set temperature (factory setting) when shortest
heating up time is important.
Precise mode: enables heating up without overshooting for temperature-sensitive
samples.
▪Calibrate:
This function allows to change the temperature measured by sensor in a range of
-5 °C to +5 °C.

Deactivate and activate safety functions
If temperature is measured via external temperature sensor Pt 1000, the error control
switches off heating:
▪at sudden temperature decrease at sensor (error E21)
▪if temperature increase at sensor is too slow in correspondence to heating power
(error E22)
These safety functions are factory preset. If necessary you can deactivate these 2 safety
functions.
Warning:
Risk of burning! Possible damage of device
Described safety functions switch off heating including when
temperature sensor is not positioned in sample.
When temperature sensor is not positioned in sample, the sensor
measures ambient temperature. The hotplate keeps up raising
temperature till max. temperature of 300 °C but set temperature can
never be reached.
When deactivating these 2 safety functions:
▪Ensure that temperature sensor is always inserted in sample prior
to switch on heating.
▪Never ll in sample to already heated up sample during running
operation, if temperature differs to already heated up sample.
✓Temperature sensor is connected and
