1.Safety Instructions
Warning!
Read the operating instructions carefully
•
before use.
Ensure that only trained staff works with the
•
instrument.
Risk of burn!
Caution when touch the housing parts and
•
the hotplate which can reach temperature of
550℃.
Pay attention to the residual heat after
•
switching off.
Protective ground contact!
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 area on a stable,
•
clean, non-slip, dry and fireproof surface. Do not operate
the instrument in explosive atmospheres, with hazardous
substances or under water.
Digital 7” Square(Hotplate)Magnetic Stirrer
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 to at least 50℃ lower
•
than the fire point of the media used.
Be aware 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 wit h the acc esso ries des crib ed
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.
Ensure that the external temperature sensor is inserted in
•
the media to a depth of at least 20 mm.
When using metal vessels, do not place the temperature
•
sensors on the bottom of the vessel. This can cause
excessively high temperatures to be measured especially
in media with poor conductivity.
3
Digital 7” Square(Hotplate)Magnetic Stirrer
The tip of the measuring sensor must be at least 5 mm
•
from vessel bottom; a distance of 10 mm is ideal.
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).
Figure 1
This device is not suitable for using in residential areas or
other constraints mentioned in Chapter 1.

7.Function: Heating
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 (PT1000) internal for temperature control are built
into the hotplate. The single external PT1000 can monitor
the temperature of sample.
If external temperature sensors needed, it must be plugged in
before the device is switched ON.
Ensure the external temperature sensor connect firmly
•
before heating.
Set the temperature via turning the temperature control
•
knob slowly to the ideal value.
When the heating function is switched on, the LED
•
“Heat”will light up and the LCD will display the real
temperature.
The rated temperature will be displayed on the right-hand
•
side of the LCD as well as Temp and℃ characters.
The heating function is switched on or off by pushing
•
heating knob.

In order to ensure the accuracy of the temperature inside
the container, please use the external temperature sensor
PT1000.

Manufacture’s standard accessory. If the sensor is not
plugged in,“Probe”will flash. If plugged in,“Probe”
will be shown on the digital display to indicate the sensor is
operating. The setting value of external temperature sensors
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 precisely.
Warning
Do not insert or remove sensor while heating.
！
7.2 Residual heat warning (Hot)
In order to prevent the risk of burns from a hotplate, digital
hotplate model has a residual he at w arni ng f unction.
When the heating function is switched off and the hotplate
temperature is still above 50℃,“Hot”will flash to warn
that there is a hazard of burns from the hotplate (Figure
6).When the hotplate temperature drops to below 50℃, 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 can
not be run.

7.3 Setting the safety temperature
The safety temperature can be set as follows:
Adjust the temperature setting key to set the safety
•
temperature.
8.Function: Stirring
The function“stirring”is switched on or off via rotating
stirring knob. The speed is set on the knob (100 to 1500 rpm
in steps of 10 rpm ).
When both of function heating and stirring are switched on
and those above operations are done, the LCD will shift to
the speed value and come back to the temperature value in
about 5 seconds.
9. Remote control
10
Figure 7
Digital 7” Square(Hotplate)Magnetic Stirrer
The unit can be controlled from an external PC (using the
dedicated software) via the RS232 C 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 DIN66020 Part 1. The allotment of
the bushing can be taken from Figure 7.

10.Faults
Instruments can not be power ON
•
Check whether the power cable is plugged in
-
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.
Temperature can switched on not reach set point
•
Check whether the safety temperature value is set too
-
low.
Stir speed can not reach set point
•
Check whether the stirring bar breakaway monitoring
-
is ON.
Excessive medium viscosity may cause abnormal
-
speed reduction of the motor.
Heating or stirring function do not start when knob is
•
pressed.
Check whether the unit is in the mode setting program,
-
Exit from the mode setting and restart the heating/
-
stirring functions.
Unit do not power down when switched off.
•
Check if the residual heat warning function is still ON
-
and hotplate temperature is above 50℃(the LCD still
works and“Hot”flashes).
If these faults are not resolved,please set the instruments
to factory default setting or take the unit to technical service
center.
