- The instrument is not running smoothly, or container moves on the base plate

3. Temperature must always be set to at least 50 °C lower than the fire point of the

media used.

4. Be aware of hazards due to:

- Flammable materials or media with a low boiling temperature

- Overfilling of media

- Unsafe container

5. Process pathogenic materials only in closed vessels.

6. Check the instrument and accessories prior to each use. Do not use damaged components. Accessories must be securely attached to the device and can not come off by themselves. Always disconnect the plug before fitting accessories.

7. When the external temperature sensor needed, the tip of the measuring sensor must be at least 5-10 mm from vessel bottom and wall.

8. The instrument can only be disconnected from the main power supply by pulling out the main or the connector plug.

9. The voltage stated on the label must correspond to the main power supply.

10. Ensure that the main power supply cable does not touch the hotplate. Do not cover the device.

11. Forbid to put pressure and over heat media on the surface of glass ceramic that can be caused surface broken.

12. The instrument may only be opened by experts.

13. Keep away from high magnetic field.

14. Do not use this instrument in an explosive environment; This instrument has no explosion-proof function

5. 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)

Figure 1

This device is not suitable for using in residential areas or other constraints mentioned in Chapter 1.

8. Trial run

Make sure the required operating voltage and power supply voltage match.

Ensure the socket properly grounded.

Plug in the power cable ,ensure the power is on and begin initializing.

Add the medium into the vessel with an appropriate stirring bar

Place vessel on the work plate.

Set the target heating time.

Set the target temperature and start heating.

Stop the heating 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 your local dealer /supplier.

Warning!

Forbid to transfer the vessel when the instrument working.

9. Working with external temperature sensor

Figure 7

9.1 LCD digital hotplate model

The external temperature sensor PT1000 is manufacture's standard accessory. If the sensor is plugged in, "Probe" will be shown on the LCD digital display to

indicate the sensor is operating. The setting value of external temperature sensor and actual temperature are displayed. Safe circuit controls hotplate temperature.

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 dealer/supplier for support.

9.2 LED digital hotplate model

The external temperature sensor PT1000 is the manufacture's standard accessory. If the sensor is plugged in and rotate the heating knob, LED displays the

temperature setting value and shifts to real value in 5 seconds. Safe circuit controls hotplate temperature. 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 he media heated.

Switch ON the instrument and run heating function.

If the heating function does not work, please contact manufacturer/supplier for technical support.

10. Residual heat warning( HOT)

In order to prevent the risk of burns from the hotplate, the unit 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 screen immediately, just pull out the plug directly. When the power OFF, the residual heat warning function cannot be run.

11. Remote Control (LCD Digital model)

Figure 8

The unit can be controlled from an external PC (using the dedicated software) via the RS232C serial interface fitted to the unit. Data communication from laboratory instrument to computer is only possible on demand of the computer.

The functions of the interface lines between laboratory instrument and automation system are selected from the specified signals of the EIA-standard RS232C, corresponding with DIN 66020 Part 1. The allotment of the bushing can be taken from Figure 8.

Transmission method: Asynchronous signal transmission in start-stop-operation.

Mode of transmission: Fully Duplex. 1 start bit; 7-character bits; 1 parity bit [straight (even]); 1 stop bit.

Transmission speed: 9600 bit/s

Start remote control knob, LCD displays "Remote ".

Note:

Forbid to insert or remove the RS232C communication line when switch ON!

12. Faults

1. Instruments can't be power ON

- Check whether the power line is unplugged

- Check whether the fuse is broken or loose

2. Fault in power ON self test

- Switch OFF the unit, then switch ON and reset the instruments to factory default setting.

3. Stir speed cannot reach set point

- Excessive medium viscosity may cause abnormal speed reduction of the motor

4. Unit cannot be powered OFF when switched OFF.

- Check if the residual heat warning function is still ON and hotplate temperature is above 50 °C(the LCD screen still work and "Hot" flash).

5. Fault error

(Applicable to machine models: LCD digital model)

Describe& conditions	code	conditions
The temperature sensor is incorrectly placed or not put into the container during heating. The temperature rises less than 2 °C after 7 minutes of heating	ER9	1. he setting temperature shall be more than the initial temperature displayed on the screen +10°C 2. The initial temperature displayed on the screen shall be less than 35°C . 3. he temperature shall rise within 2°C after heating for 7min.

If these faults are not resolved, please contact dealer/ suppler.

13. 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
Cosmetics	Water containing tenside /Isopropyl alcohol
Foodstuffs	Water containing tenside
Fuels	Water containing tenside

Wear the proper protective gloves during cleaning of the instrument.

Before using other method for cleaning or decontamination, the user must ascertain with the manufacturer that this method will not harm the instrument.

Send in the case of service the instrument back in the packaging carton. Storage packing is not sufficient for the back dispatch. Use additionally a suitable transportation packing.

The enamel makes the hotplate easier to care for and more resistant to acids and bases. Because of it, 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.

Warning!

Power OFF when maintenance and cleaning.
