Safety instruction
•Read the instructions carefully before use
•Make sure that only qualified personnel use this tool
•Do not heat easily flammable or highly volatile substances
•Be very careful when touching the heating plate. It can reach a temperature
of 340 ° C.
•Be careful even when the instrument has been turned off because the plate
remains hot even for a long time.
•Before use, make sure that the instrument is connected to an earthed socket
•During work, staff must prevent risks of:
oSplashing and / or evaporation of liquids;
oEmission of toxic or combustible gases.
•Place the instrument in a suitable area, on a stable, clean, non-slip, dry and fireproof surface;
•Do not use the instrument in explosive atmospheres, containing dangerous substances or under water;
•Gradually increase the stirring speed;
•The set heating temperature must always be at least 25 ° C lower than the combustion temperature of the
heated substance used;
•Pay close attention to the risks due to:
oFlammable materials or samples with low boiling temperature;
oExcessive filling of samples;
oUnsafe and / or unsuitable containers for heating;
•Use any pathogenic samples only in closed containers;
•Check that the instrument and accessories are in optimal condition before use. Never use damaged
components. Optimal safety and operation are guaranteed only if the instrument and accessories described
are in order. The accessories must also be firmly connected to the device;
•The instrument can be disconnected by disconnecting it from the power supply or by disconnecting the cable;
•The operating voltage indicated on the instrument label must correspond to that of the network to which it is
connected;
•Make sure that the power cable does not touch the heating plate;
•The tool can only be opened by specialized technicians;
•Keep the instrument away from electromagnetic fields;
•Respect the minimum distance between the devices and between the device and the wall (minimum 10 cm).

Description
Temp e °C
These icons appear when the function heating is active.
Stir
This icon appears when the stirring function is active.
Mode
View the working mode.
Hot
Warns of the possibility that the plate is still too much hot
and therefore potentially dangerous. This function is also
active when the function is deactivated heating if the
plate temperature is above 50 ° C.
Probe
The external probe is connected to the instrument.
Remote
The instrument is controlled remotely.
Err
Displays an operating error.
Valore reale e valore impostato
Display of the heating and / or stirring parameters in
progress.
Note: If the heating and stirring function were started at the same time, the display of the "heating" function always
has priority. If the speed is changed, the new value is displayed for 5 seconds.
Operating modes
Operating mode A
The user can adjust the parameters via the front controls or via a PC connected to the RS232 port.
The residual temperature safety function, the safety temperature limit and the automatic braking function for detaching
the magnetic anchor, can be changed.
Operating mode B
This mode is active only with an external probe connected.
The user can adjust the parameters via the front controls or via a PC connected to the RS232 port.
The residual temperature safety function, the safety temperature limit and the automatic braking function for detaching
the magnetic anchor, can be changed.
Operating mode C
The instrument keeps in memory the last speed and temperature settings set before the last shutdown.
PC remote control can be used but without the connection of the external probe.
The residual temperature safety function, the safety temperature limit and the automatic braking function for detaching
the magnetic anchor, CANNOT be changed.
Heating function
The device control system is digital and the temperature control system in particular has two separate safety circuits.
The plate is kept at a constant temperature by a digital control circuit. The plate temperature is monitored by two
internal temperature sensors (Pt1000) integrated in the plate itself. The external Pt1000 probe is able to monitor the
temperature of the heated sample.

If you need an external temperature probe, it is advisable to connect it before turning on the instrument.
Procedure:
•Make sure that any external probe is well connected to the instrument.
•Set the temperature using the adjustment knob and bring it to the desired value.
•When the heating function is active, the “Heat” LED lights up and the display indicates the real temperature.
•The set temperature will be displayed on the right side of the screen.
•The heating function is turned on / off by pressing the temperature
adjustment knob.
Operation with external temperature probe inserted
The word "Probe" will appear permanently on the display to indicate that the sensor
is operating.
Basic stirring
The stirring function is activated or deactivated by pressing the stirring speed adjustment knob. The speed can be set
between 100 and 1500 rpm in 10 rpm steps. When both functions are active and all speed adjustment operations have
been performed, the display returns to the speed and temperature display in about 5 seconds.
Remote control
The instrument can be controlled from an external PC (through
the appropriate software) through the RS232 serial port located
on the back of the instrument.
The possible transmission of data to the PC is possible only at the
request of the PC itself.
•Transmission method: Asynchronous signal
•Transmission mode: Fully Duplex.
•Transmission speed: 9600 bit / s
Malfunctions
• In case of instrument failure, it is recommended to turn it off;
• Turn off the main ON / OFF switch for a few seconds and turn the unit back on;
• The stirring function will continue to operate at the set speed before the fault occurs;
• The heating function will continue to operate at the set temperature before the fault occurred;
• If the problem is not resolved, contact technical support.
