5. Trial Run
•
Make sure the required operating voltage and power supply voltage match.
•
Ensure that the socket is 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 (S03D series and H03D series).
•
Set the target temperature and start heating.
•
Observe the LED display (H03D series).
•
Stop the heating and stirring functions.
If the operations above cause no abnormalities, the device is ready to operate. Otherwise, the device
may have been damaged during transportation, please contact manufacturer/supplier for technical
support.
Warning!
Forbidden to transfer the vessel while
the instrument is working.
6. Function: Heating (H03D series)
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 internal
temperature sensors for temperature control are built into the hotplate. The single external PT1000
can monitor the temperature of the sample.
•
If using an external sensor PT1000: Always connect it to the device BEFORE turning the power
on and insert it into the sample BEFORE heating (see section 6.1).
•
Set the temperature by rotating the temperature control knob slowly towards the target value.
•
While the heating function is on, the LED screen displays the temperature value on the left-hand
side.
•
The heating function is switched on or off by pushing the heating knob.
The heating function will be stopped automatically under abnormal conditions. The safe circuit
keeps the hotplate temperature under 320°C.
