1. Introduction
The AREX-6 Digital PRO heating magnetic stirrer is used in the laboratory for general use and for all those applications that require a
precise regulation for stirring speed and heating liquids.

The Aluminum alloy heating plate with ceramic coating (1) ensures:
• Optimum heat distribution and a high specific power thanks to the circular configuration
• Temperature homogeneity
• High resistance to thermal stress and thermal shock
• High resistance to chemical agents and surface abrasion
Magnetic stirring is generated by an AlNiCo magnet, driven by brushless motor which offers a virtually unlimited duration.
Size and shape of the magnetic stir bar determines the stirring efficiency at any given speed.
The stirring bar which satisfies most applications is Ø8x40mm.
NOTE: The vessel must be made of a suitable material to withstand the foreseen temperature.
NOTE: Using the heating plate at high temperatures may cause discoloring. This does not alter the thermal, mechanical and chemical
resistance of the plate in any way.
2. Assembly and installation
•Unpacking
- Check the integrity of the unit after unpacking.
•The box includes
- AREX-6 Digital PRO heating magnetic stirrer
- Power supply cord
- Instruction manual
•First installation
- Place the unit on non -flammable surface
- Make sure that the values on the rating plate, correspond to those of the power supply
- Move the main switch (2) to the OFF position
- Ensure that the socket provided with grounding is accordant to current safety norms and easy to reach. Use only the cable
provided with the instrument.
- Insert the mains power cable into the socket
NOTE: the mains cable must remain far away from the hot plate. It can be substituted only by main cables with same features (T=90°C,
connector C15)

VTF
➢Move the main switch to off position
➢Screw the threaded support rod into its seat on the back of the instrument
➢Fasten the VTF thermo-regulator onto the support rod
➢Place the temperature probe in the flask
➢Plug the VTF into the dedicated socket on the back of the instrument
➢Switching on the instrument through the main switch, the probe led (A) turns on and display shows OFF
➢Select operating temperature on VTF and after clicking temperature control knob, a dashed line (----)
appears on the display
NOTE: while VTF is inserted, it is not possible to set any temperature turning the knob on the instrument.
The plate can heat until the maximum temperature set in the full scale (see chapter 5, “Temp Limt”).
It is possible to set the timer on the VTF only.
External probe
➢Move the main switch to off position
➢Screw the threaded support rod into its seat on the back of the instrument
➢Fasten the clamp onto the support rod
➢Place the temperature probe in the flask
➢Plug the probe into the dedicated socket on the back of the instrument
➢Switching on the instrument through the main switch, the probe led (A) turns on and display shows OFF
➢Select operating temperature using the temperature control knob
➢Click the knob to start heating
➢The display shows the real temperature obtained by the probe. Each 3 seconds the temperature set point
is shown on the display and the temperature set point led (C) turns on
Commissioning
➢Switch on the instrument through the main switch (2)
➢Display shows software version, the last set point values and OFF on both displays (if “Start mode” is
set on Stop, see chapter 5)
Stirring
➢Adjust motor speed set point by turning the speed control knob (3)
➢Click the knob to start stirring
➢The speed increases until set point achievement
➢A microprocessor ensures constant speed even when the viscosity changes (counter-reaction)
➢Switch off the stirring by clicking the knob
Heating
➢Adjust heating plate temperature set point by turning the temperature control knob (4)
➢During all the time of set point adjusting, the temperature set point led (C) is switched on
➢Click the knob to start heating
➢Display shows real plate temperature for 3 seconds and temperature set point for 1 second
alternatively
➢When temperature set point is visualized, the relative led (C) turns on
➢While the instrument is heating, the Heating ON led (B) turns on
➢Switch off the heating by clicking the knob
➢When heating function is off and the heating plate temperature exceeds 50 °C, the message “Hot” is
shown on the temperature display until temperature falls below 50 °C
NOTE: this warning is not active if the instrument is not powered.
NOTE: in case of black-out, once the power is back the device restarts in the set start mode
(see chapter 5 “Strt mode”)
Timer
➢To access the timer function, push the Timer/autoreverse button (F)
➢On the displays are visualized
➢Set the timer turning the speed control knob until the desired value and click to confirm
➢Timer led (D) turns on
➢Timer countdown starts when one of the main functions is on or when temperature reaches set point
value (see chapter 5, “Time Strt”)
➢When countdown is active, timer led flashes
➢Esc timer menu: a) click twice timer/autoreverse button
b) wait 5 seconds without touching any knob
➢When timer countdown ends, is shown until operator action.
It’s possible stirring continues if the parameter “time Sped” is ON (see chapter 5)
Autoreverse
➢To access autoreverse function push twice the Timer/auto reverse button (F)
➢On the displays are visualized
➢Set the autoreverse turning the speed control knob until the desired value and click to confirm
➢The autoreverse led (E) turns on
➢Autoreverse starts when stirring is on

5. Setting mode
Press both knobs for 3 seconds to enter into the setting mode when heating and stirring are off.
Clicking the Timer/autoreverse button (F) it is possible to pass from one of the following parameter to the next ones:
Click the stirring control knob to visualize the set value. Turn the knob to set the new value and click to confirm.
To esc setting mode wait 10 seconds without touching any knob or push both knobs at the same time.
* The temperature control function of the heating plate can also be used as a safety thermostat. In this case the maximum temperature of
the heating plate will not exceed the full scale temperature set on the AREX-6 Digital/Digital PRO meaning that a longer heating time is
required in order to reach the temperature set with VTF or external probe inserted, but reducing temperature oscillation at set point value.
