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 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. 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.
Warning!
•Read the operating instructions
carefully before use.
•Ensure that only trained staff works with the
instrument.
Risk of burn!

hotplate which can reach temperature of 500
℃.
•Pay attention to the residual heat
after switching off.
Protective ground contact！
•Make sure that socket must be
grounded
(protective ground contact) before use.

•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

6. Working with external temperature
sensor
Connection PT1000 Fuse
Figure 7
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.
7.
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℃, 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.
8. Logging function
Figure 8
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,
