Trial Run
• Make sure the required operating voltage and power
supply voltage match.
• Ensure the socket must be 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 stirring speed and begin.
• Observe the stirring bar and LED display (digital model).
• Set the target temperature and start heating.
• Observe the LED display (digital hotplate model).
• Stop the heating and stirring functions.
If these operations above are normal, the device is ready to
operate. If not, the device may be damaged during
transportation, please contact manufacturer/supplier for
technical support.
Warning !
Forbid to transfer the vessel when the instrument
working.

Function:
Heating
(
Digital
hotplate model )
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 internal for temperature control are
built into the hotplate. The single external PT1000 can
monitor the temperature of sample.
•
Plug in the external PT1000.
•
Set the temperature via rotating the temperature
control knob slowly to the target value.
•
When the heating function is switched on, the LED
displays the temperature value on the left-hand side.
•
The heating function is switched on or off by pushing
heating knob.
The instrument automatically displays the last running
speed and temperature parameters once turned on.
Generally, the LED screen cannot display the actual
temperature of sample in the vessel or hotplate surface,
temperature differences as following:
