1 Safety notes
Please read this manual carefully and completely before you use the device for the first time. The
device may only be used by qualified personnel and repaired by PCE Instruments personnel.
Damage or injuries caused by non-observance of the manual are excluded from our liability and
not covered by our warranty.
•The device must only be used as described inthis instruction manual.If used otherwise,
this can cause dangerous situations for the user and damage to the meter.
•The instrument may only be used if the environmental conditions (temperature, relative
humidity, …) are within the ranges stated in the technical specifications. Do not expose
the device to extreme temperatures, direct sunlight, extreme humidity or moisture.
•Do not expose the device to shocks or strong vibrations.
•The case should only be opened by qualified PCE Instruments personnel.
•Never use the instrument when your hands are wet.
•You must not make any technical changes to the device.
•Keep the surface clean and free from damage. Clean it only with protective gloves. The
device should only be cleaned with a soft cloth.
•The device must only be used with accessories from PCE Instruments or equivalent.
•Before each use, inspect the case for visible damage. If any damage is visible, do not
use the device.
•The device must not be used in a potentially explosive atmosphere, must not come into
contact with hazardous substances or be submerged.
•Place the magnetic stirrer on a flat, stable, clean, non-slip and fireproof surface.
•Make sure that only authorised persons who have previously familiarised themselves
with the operating instructions use the magnetic stirrer.
•Note that magnetic fields can affect pacemakers and cause data loss.
•Do not touch the heating plate when it has reached atemperature above 50°C to avoid
injury / burns. Please note that there is still residual heat even after switching off.
•Do not place any objects on the stirring plate that are not temperature-resistant.
•Hold the instruments firmly in both hands when moving or connecting it. The unit should
not be moved until it has reached room temperature.
•Make sure that the power cable and temperature sensor do not come into contact with
the heating plate.
•Do not place any steel or magnetic parts on the magnetic stirrer. The recommended
magnetic stirring bar may only be placed on the device if it is in a beaker or flask.
•Depending on the medium, you should wear appropriate protective equipment. With
some media, there is a risk of splashing or the release of toxic or flammable gases, for
example.
•Damaged cups, flasks, stirring bars or other parts should not be used anymore.
•Reduce the speed if the medium splashes out of the container due to excessive speed,
if the device runs unsteadily or if the container moves back and forth on the plate.
•Do not move the instrument during operation or when it is connected to the power
supply.
•Do not use the appliance for hazardous or reactive solutions.
•Special care should be taken when working with flammable materials, especially if they
have a low vapour pressure. Overfilling should also be avoided in any case. The
container should be the right size and stand firmly on the plate. Broken glass can also
be a hazard.
•Contamination and chemical reactions must be expected.
•The temperature sensor must always be immersed at least 30 mm deep in the medium.
•Please observe the specified operating voltage.

•Pathogenic substances should always be processed in a closed container and using a
suitable extraction hood.
•Only use media that you know will not react dangerously to the additional energy
generated during processing. Additional energy can also be generated by light
irradiation, a certain ambient temperature or other factors.
•Under certain circumstances, abrasion debris from dispersion and stirring devices can
get into the medium to be processed.
•For dissolved alkali metals or alkaline earth metals and at temperatures above 250 °C,
only glass-coated magnetic stirring bars should be used.
•Do not cover the appliance either partially or completely with metal plates or sheets as
this can cause overheating. Always keep the mounting plate clean.
•Make sure that the socket is earthed (protective contact).
•Do not use the instrument if theceramic surface is damaged, i. e. if it has, for example,
scratches, rust or splinters.
•Non-observance of the safety notes can cause damage to the device and injuries to
the user.
We do not assume liability for printing errors or any other mistakes in this manual.
We expressly point to our general guarantee terms which can be found in our general terms of
business.

•Keep the original packaging in case the magnetic stirrer needs to be returned to us.
•Carefully remove the appliance from the packaging and place it on a firm, level
surface. This should be non-slip and not prone to vibration. All four feet should stand
firmly on the surface. The supplied accessories should also be carefully unpacked
and removed.
•The ambient temperature should ideally be 25 °C and direct sunlight should be
avoided.
•Keep a distance of at least 20 cm from other objects all around to ensure optimum
cooling efficiency.
•Keep the instrument away from heated solutions to avoid effects on the sample
temperature.
•Do not place the magnetic stirrer in places that are difficult to access.
•Screw the support rod as far as it will go into the thread provided on the back of the
unit.
•Attach the sensor holder to the support rod using the cross clamp.
•Connect the power cable to the socket on the back of the unit and to your power
supply.
•Make sure that the input voltage is correct.
•Align the sensor holder so that the tip of the temperature sensor is immersed at least
30 mm deep in your stirring medium. Then connect the temperature sensor to the
green socket on the back of the instrument.
