Safety instructions
·When operating the magnetic stirrer, please follow the safety instructions, the accident prevention regulations, and pay attention to your
occupational health.
· Notice: Effects of magnetic field should be taken into account(e.g.data storage, cardiac pacemakers...)
· Risk of burns! The heating plate can reach a high temperature of 280 °C when the stirrer is working. Please exercise caution when
touching the outer housing and the heating plate. Pay attention to the residual heat even after the instrument is shut down.
!
· Ensure that the power cord does not make contact with the heating plate.
· Wear appropriate protective equipments when operating.
!
Otherwise there may have risks from:
- Splashing of medium
- Ejection of stirrer bar
- Release of toxic or flammable gases
·Place the instrument on a stable, clean, anti-slip, dry and fireproof surface.
·Ensure the base of instrument is clean and intact.
·Check and ensure the instrument and accessories remain intact before each use. Do not use damaged components.
·Slowdown the speed if
- The medium splashes out of container in high speed
- The container shifts on the plate
· Beware of hazards due to:
!
- Flammable materials
- Low-boiling flammable medium
- Improper container size
- - Overflows of the medium
The container is in an unsafe condition
• The instrument may be heated up under normal use.
• The medium in the container can still be heated up due to high speeds rotation of the magnetic stirrer bar, even if the heating function is
not on.
• Process pathogenic materials only in airtight container within a suitable fume hood.

Setting safety temperature
Notice！ If using an external temperature sensor (Pt1000s) to measure the temperature of the liquid medium, user must connect the

04661-42
external temperature sensor and probe into the liquid medium before activating the heating function. Do not remove the external
temperature sensor during the heating, otherwise the internal components will be damaged.
Do not set the safety temperature higher than the ignition point of the medium used. The safety temperature should be set at least
!
25 degrees lower than the ignition point of the medium.
1
Press (Power on/off) until standby indicator goes off and the system enters into setting operation status. The LCD screen will be
lightened and (Plate safety temperature icon) will flash showing that the system is now in the setting area of plate safety
temperature;
2
When the safety temperature setting is switched on, then touch and move your
finger around the “Touch wheel” (clockwise+ / counterclockwise-) to adjust the
setting data of safety heating temperature with the adjustable increment of 1°C,
and total adjustable range is . After setting the safety temperature,
50°C ~360°C
the heated top plate temperature will not exceed the setting safety temperature
to keep the liquid medium from damage;
3
After the safety temperature is finished, press (Start/Stop) or “Switch” key to record and save the safety temperature
setting and system will automatically switch to heating temperature setting area;
If the safety temperature is not been set in 15 second, the indicator on the LCD screen will be deemed to be the safety heating
temperature and the system will automatically switch to heating temperature setting area;
The safety temperature can only be set right after pressing button, and cannot be set again during operation. Once the safety
heating temperature is set, it cannot be adjusted again until next start up.
Notice
The setting of plate safety temperature is to make sure the sample liquid will not be damaged. However if the initial plate
!
temperature is too low, it will slow down the heating speed, therefore, if the plate temperature, considering the sample liquid ,
is allowed to be set higher than the safety temperature, please set the plate to the highest safety temperature 360°C, it will
help to accelerate the heating speed.

04661-42
Problem
Instruments does not power on
Stir bar bounces irregularly
Stir bar does not rotate
Figures on LCD flash for no reason
or operation key does not function
Possible causes
The power line and the power outlet
is disconnected
The power socket is in poor electrical
contact condition or un-powered
Container is too far from plate center
Mismatch of stir bar specifications and models
Irregularities in the shape of the stir bar and of
the bottom of the container
The material of the container is Fe or Cu
which will be magnetized
If container diameter is same as stir bar length.
When stirring speed is slow, stir bar touches the
container which leads to stop
The power voltage is lower
Solutions
Make sure the power line correctly
connected with the power socket
Replace the power outlet with the one in
good electrical contact condition
Position directly on center of plate
Use stir bar recommended for model
Increase or decrease the speed until the
stir bar begins to rotate evenly
Use glass or 304 stainless steel container
Use a big container or change to shorter
stir bar
Turn off other high power instrument or add
another A.C.stabilized voltage power supply

How to use the touch wheel
Touch and move your finger around the “Touch wheel”
clockwise+ / counterclockwise- (follow the direction of
the arrow) to adjust the setting of different configuration
with the adjustable increment. The faster
the movement of the finger the larger
the adjustment of the setting parameter
and vice versa so that one can rapidly
adjust to the desired configuration zone
and then slow down the finger movement
to accurate position.

Troubleshooting guide
Before contacting your supplier in case of issue, please check below for troubleshooting some common issues.
Problem
Instruments does not power on
Stir bar bounces irregularly
Stir bar does not rotate
Figures on LCD flash for no reason
or operation key does not function
Possible causes
The power line and the power outlet
is disconnected
The power socket is in poor electrical
contact condition or un-powered
Container is too far from plate center
Mismatch of stir bar specifications and models
Irregularities in the shape of the stir bar and of
the bottom of the container
The material of the container is Fe or Cu
which will be magnetized
If container diameter is same as stir bar length.
When stirring speed is slow, stir bar touches the
container which leads to stop
The power voltage is lower
Solutions
Make sure the power line correctly
connected with the power socket
Replace the power outlet with the one in
good electrical contact condition
Position directly on center of plate
Use stir bar recommended for model
Increase or decrease the speed until the
stir bar begins to rotate evenly
Use glass or 304 stainless steel container
Use a big container or change to shorter
stir bar
Turn off other high power instrument or add
another A.C.stabilized voltage power supply
