Safety Instructions For your protection • Read the operating instructions in full before starting up and follow the safety instructions when in use. • Ensure that only trained staff work with the device. • Socket must be earthed (protective ground contact) • Caution-Magnetism! Effects of the magnetic field have to be taken in to account (e.g. data storage media, cardiac pacemakers…). • The heating plate can reach temperatures of 310°C and pay attention to the residual heat after switching off.
- flammable materials - combustible media with a low boiling temperature - glass breakage - incorrect container use - overfilling of media - unsafe condition of container • The machine may heat up when in use. Don’t use the machine in explosive atmospheres with hazardous substances. • Process pathogenic materials only in closed containers under a suitable extractor hood. • Only process media that will not react dangerously to the extra energy produced in other ways, e.g. through light irradiation.
distance between the machine and the wall is mini. 100mm. Inspection • Unpack the device carefully and check for any damages which may have arisen during transit. Please contact the manufacturer/supplier for technical support. Note: If there is any apparent damage to the device, please do not connect the power line.

When the heating temperature is higher than the safety temperature, Knob for safety temperature the machine stops heating heating. It ’s the max. setting temperature of 320°C by rotating the knob to the limit in the clockwise direction; it'll be min.
Trial run • Make sure the required voltage corresponds to the mains voltage. • Ensure the socket must be properly grounded. • Switch on and start initializing. • Add sample into the container with an appropriate stirring bar. • Place the container on the working plate. • Set the target speed and start stirring. • Observe the stirring bar operation. • Set the temperature and start heating • Connect the external temperature sensor. If the above operations are normal, the device is good to run.
please use the external temperature sensor PT100. internal for temperature control are built into the hotplate. The single external PT100 can monitor the temperature of sample. Working with the external temperature sensor The external temperature sensor PT100 is an optional accessory. When the sensor is connected, the sensor indicator will light and the machine is in the PT100 operation mode. The setting temperature of the external sensor and the actual temperature are displayed.
Stirring Stirring is switched on / off by pressing the speed setting knob. The speed is set by rotating the knob in the range of 50-1500rpm.
• Do not allow moisture to get into the device when cleaning. • Disconnect the main plug when cleaning. • Wear protective gloves when cleaning. • Only use the recommended cleansing agents.
