with the
instrument.
Risk of burn!
•C
aution when touch the housing parts and
the hotplate which
can reach temperature of
280°C.
•Pay attention to
the residual heat after
switching off.
Protective ground contact
ʽ
•Make sure that socket must be
grounded
(protective ground contact) before use.
• When working wear personal safety guards to avoid the
risk from:
- Splashing and evaporation of liquids
- Release of toxic or combustible gases
• Set up the instrument in a spacious are on a stable, clean,
non-slip, dry and fireproof surface. Do not operate the
instrument in explosive atmospheres, with hazardous
substances or under water.
• Gradually increase the speed, reduce the speed if:
- Stirring bar breaks away due to high speed
- The instrument is not running smoothly, or container
moves on the base plate
•Temperature must always be set at least 50ćlower than
the fire point of the media used.
•Beaware of hazards due to:
- Flammable materials or media with a low boiling
temperature
- Overfilling of media
- Unsafe container
• Process pathogenic materials only in closed vessels.
• Check the instrument and accessories prior to each use.
Do not use damaged components. Safe operation is only
guaranteed with the accessories described in the
“Accessories” chapter. Accessories must be securely
attached to the device and can not come off by themselves.
Always disconnect the plug before fitting accessories.
•When the external temperature sensor needed, the tip of
the measuring sensor must be at least 5-10mm from vessel
bottom and wall.

• The instrument can only be disconnected from the main
power supply by pulling out the main or the connector plug.
• The voltage stated on the label must correspond to the
main power supply.
• Ensure that the main power supply cable does not touch
the hotplate. Do not cover the device.
•The instrument may only be opened by experts.
• Keep away from high magnetic field.
2. Proper Use
The instrument is designed for mixing and/or heating
liquids in schools, laboratories or factories.
•Observe the minimum distances between the devices,
between the device and the wall and above the assembly
(min. 100 mm)
>100mm
Figure 1
This device is not suitable for using in residential areas or
other constraints mentioned in Chapter 1.

5. Trial Run
• Make sure the required operating voltage and power
supply voltage match.
•Ensure the socket must be properly grounded.
• Plug in the power cable⧎ensure the power is on and begin
initializing.
•Addthemedium into the vessel with an appropriate
stirring bar.
•Place vessel on the work plate.
•Set the target stirring speed and begin.
•Observe the stirring bar and LED display (digital model).
•Set the target temperature and start heating.
•Observe the LED display (digital hotplate model).
•Stop the heating and stirring functions.
If these operations above are normal, the device is ready to
operate. If not, the device may be damaged during
transportation, please contact manufacturer/supplier for
technical support.
Warning !
Forbid to transfer the vessel when the instrument
working.
6. Function: Heating ( Digital
hotplate model )
The device is controlled by digital temperature control
technology, which has two separate safe circuits. The
hotplate is kept at a constant temperature by a digital
control circuit. The hotplate temperature can also be
monitored from a separate, adjustable safe circuit. The two
temperature sensors internal for temperature control are
built into the hotplate. The single external PT1000 can
monitor the temperature of sample.
•Plug in the external PT1000.
•Set the temperature via rotating the temperature
control knob slowly to the target value.
•When the heating function is switched on, the LED
displays the temperature value on the left-hand side.
•The heating function is switched on or off by pushing
heating knob.
The instrument automatically displays the last running
speed and temperature parameters once turned on.
Generally, the LED screen cannot display the actual
temperature of sample in the vessel or hotplate surface,
temperature differences as following:

9
-Hotplate center and outer edge.
-The sample in the vessel and hotplate surface.
In order to ensure the accuracy of the temperature inside the
container, please use the external temperature sensor
PT1000.
6.1 Working with external temperature
sensor
Figure 6
The external temperature sensor PT1000 is the
manufacturer’s standard accessory. When PT1000 sensor is
connected and rotate the temperature control knob, LED
displays the temperature setting value and shifts to real
value in 5 seconds. Safe circuit controls hotplate
temperature under 320°C. Comparing with the temperature
control of the hotplate, the external temperature sensor can
control the medium’s temperature more precise. The
heating function will be stopped automatically under
abnormal conditions. Please operate follow the instructions
below:
•Switch OFF the instrument.
•Ensure the external temperature sensor is inserted in
the media heated.
•Switch ON the instrument and run heating function.
If the heating function does not work, please contact
manufacturer/supplier for technical support.
6.2 Residual heat warning˄
˄
HOT
˅
In order to prevent the risk of burns from a hotplate, digital
hotplate has a residual heat warning function. When the
heating function is switched off and the heating plate
temperature is still above 50°C, “Hot” will flash to warn
that there is a hazard of burns from the hotplate. When the
unit is powered off, the LED screen displays the
temperature of hotplate and Hot in turn. When the hotplate
temperature drops to below 50°C, the unit will
automatically switch off. If users want to turn off the LED
immediately, just pull out the plug directly. When the plug
is pulled out, the residual heat warning function cannot be

10
run.
7.Stirring
The function “stirring”of LED digital model is switched
on or off via pushing on/off speed control knob. The
speed range of to 1500 rpm and in steps of 10 rpm.
The function “stirring” of classic model is switched on
or off via rotating speed control knob. The speed range of
0 to 1500 rpm.
8. Faults
•Instruments can’t be power ON
-Check whether the power line is unplugged
-Check whether the fuse is broken or loose
•Fault in power on self test
-Switch OFF the unit, then switch ON and reset
the instruments to factory default setting.
•Stir speed cannot reach set point
-Excessive medium viscosity may cause abnormal
speed reduction of the motor
•Unit cannot be powered off when switched off.
-Check if the residual heat warning function is still
ON and hotplate temperature is above 50ć(the
LED screen still work and “Hot” flash).
If these faults are not resolved, please contact
manufacturer/supplier.

9. Maintenance and Cleaning
•Proper maintenance can keep instruments working
properly and lengthen its lifetime.
•Do not spray cleanser into the instrument when
cleaning.
•Unplug the power line when cleaning.
•Only use recommended cleansers:
Dyes
Isopropyl alcohol
Construction materials
Water containing tenside
/ Isopropyl alcohol

Water containing tenside
•Before using other method for cleaning or
decontamination, the user must ascertain with the
manufacturer that this method will not harm the
instrument. Wear the proper protective gloves during
cleaning of the instrument.
Note:
•Electronic device can not clean with
cleanser.
•If you require maintenance service, must be
cleaned the instrument in advance to avoid
pollution
of hazardous substances, and to
send back into original packing.
•
If the in
strument will not use for a long time,
please switch off and place in a dry, clean,
room temperature and stable location.
