Heater Operation
• To avoid fires or injuries, make sure that the temperature is kept
safely below the flash point of the media to be heated.
• Be sure to wear proper protective gear (such as goggles, gloves,
masks or an apron) when using this instrument.
• This instrument can reach temperatures in excess of 350°C at the
top plate surface. Touching such hot surface will cause severe
burns.
• Even if the instrument is turned off, the surface of the top plate and
the vessel on top of it will remain very hot for some time. Never
leave your instrument accessible to others while it is hot and never
touch it unless you are absolutely sure.
• Although this instrument has a hot top warning indicator, which is
turned on when the top plate temperature is over 50°C, do not rely
on this indicator alone for your safety.
EXTREME CAUTION IS REQUIRED AT ALL TIMES!
• To avoid overheating of the media, do not set the heating level too
high from the beginning. Gradual increase of the heating level is
always recommended.
The procedures of the heating operation are as follows:
(1) To activate the heater, turn the heater knob clockwise. With a ‘click’
sound, the heating starts immediately. Set the heater knob at the
desired position. (The heater LED will illuminate only when power is
supplied to the heater. However, if you set the knob at its maximum
position, then the heater LED will remain illuminated.)
Note that the hot top warning indicator will be turned on if the top
plate temperature rises over 50°C.
