1. SAFETY INSTRUCTIONS
Warning!
• Read the operating instructions carefully before use.
• Ensure that only trained staff works with the instrument.
Risk of burn! (hotplate model)
• Caution when touching the housing parts and the hotplate they can reach temperature of 500°C.
• Pay attention to the residual heat after switching off.
Protective ground contact!
• Make sure that socket is grounded (protective ground contact) before use.
• When working wear personal safety guards avoid the risk from:
o Splashing and evaporation of liquids
o Release of toxic or combustible gases
• Set up the instrument in a spacious area that’s 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 but reduce the speed if:
o Stirring bar breaks away due to high speed
o The instrument is not running smoothly, or container moves on the base plate
• When using the hotplate model temperature must always be set to at least 50℃lower than the fire point of the
media used.
• Be aware of hazards due to:
PRODUCT CODE
DESCRIPTIONS
400.100.130
Stirrer Magnetic Hotplate up to 30L

3
o Flammable materials or media with a low boiling temperature (Hotplate model)
o Overfilling of media
o Unsafe container
• Process pathogenic materials only in closed vessels.
• In the case of the stirrer bar is PTFE, please note:
o Elemental fluorine, three fluoride and alkali metals will corrode the PTFE and Halogen alkanes makes it
expand at room temperature
o Molten alkali, alkaline earth metals or their solution, as well as the powder in second and third ethnic of
the Periodic Table of Elements will have chemical reaction with PTFE when temperature reaches 300 ~
400 ℃.
• 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 user manual. Accessories must be securely attached to the
device. Always disconnect the plug before fitting accessories.
• When using the external temperature sensor, 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 a qualified technician.
• 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 and the wall and above the assembly (min. 100 mm)
Figure 1
This device is not suitable for using in residential areas or other constraints.

Receiving Inspection
Unpack the equipment carefully and check for any damages which may have arisen during transport. Please contact
manufacturer/supplier for technical support.
Note:
If there is any apparent damage to the system, please do not plug it into the power line.

5. TRIAL RUN
• Make sure the required operating voltage and power supply voltage match.
• Ensure the socket is properly grounded.
• Plug in the power cable and ensure the power is on and begin initialising.
• Add the medium 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 LCD display (digital model).
• Set the target temperature and start heating.
• Observe the real temperature on LCD display (digital model).
• Stop the heating and stirring functions.
• If these operations above are normal, the device is ready to operate. If these operations are not normal, the
device may be damaged during transportation, please contact supplier for technical support.
Warning!
Do not transfer the vessel when the instrument is powered on.
6. USING THE EXTERNAL TEMPERATURE SENSOR
The external temperature sensor PT1000 is a standard accessory. If the sensor is plugged in “Probe” will be displayed on
the LCD digital display to indicate the sensor is operating. The setting value of the external temperature sensor and actual
temperature are displayed.
The safety circuit controls the hotplate temperature. Comparing with the temperature control of the hotplate, the external
temperature sensor can control the medium’s temperature more precisely. The heating function will be stopped
automatically under abnormal conditions. Please operate following the instructions below:
• Switch OFF the instrument
• Plug in the external PT1000
• Switch ON the instrument and run heating function
• Set the temperature via rotating the temperature control knob slowly to the target value.
If the heating function does not work, please contact the supplier for support.

7. 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 hotplate temperature drops to below 50°C, the unit will automatically switch off. If users
want to turn off the LCD immediately, just pull out the plug directly. When the plug is pulled out, the residual heat warning
function will not work.
8. LOGGING FUNCTION
The data can be saved by SD card. The process is as follows:
• With the power switch turned off, insert the SD card into the slot on the left side of the panel.
• After inserting it, turn on the power switch and operate the heating as described above. Set temperature at 1
minute intervals
• The current temperature will be logged automatically.
• The logged data can be checked in Excel format by connecting the SD card to a personal computer
SD Card
9. FAULTS
• Instruments can’t be power ON
o Check whether the power line is unplugged.
o Check whether the fuse is broken or loose.
• Fault in power on self-test
o Switch OFF the unit, then switch ON and reset the instruments to factory default setting.
• Stir speed cannot reach set point
o Excessive medium viscosity may cause abnormal speed reduction of the motor.
• Unit cannot be powered off when switched off
o Check if the residual heat warning function is still ON and hotplate temperature is above 50℃(the LCD
still work and “Hot” flash).
If these faults are not resolved, please contact supplier.

10. 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 Isopropyl alcohol
COSMETICS
Water containing Isopropyl alcohol
FOODSTUFFS
Water containing tenside
FUELS
Water containing tenside
• Before using other method for cleaning or decontamination, the user must ascertain with the
manufacturer/supplier that this method will not harm the instrument.
• Wear proper protective equipment during cleaning of the instrument.
• Send in the case of service the instrument back in the packaging carton. Storage packing is not sufficient for
despatch. Please use additional suitable packaging for transportation.
• The enamel makes the hotplate easier to care for and more resistant to acids and bases. However the hotplate is
also more susceptible to extreme fluctuations in temperature and the force of impact. This can result in cracks
forming or the coating flaking off.
Note:
• Electronic device cannot 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 instrument will not use for a long time, please switch off and place in a dry, clean, room
temperature and stable location.
