For temperature and timer setting on the Temperature Probe Control
Mode, see Temperature Setting and Timer Setting.
In case of low smoke point media heating, High temperature limit value
should be lower than smoke point. [Refer to High Temperature Limit
Setting]
(1) Temperature Probe Errors
On temperature control mode if the external probe is in the air or is not
enough socked into the media, error message will be shown on display and
heater will be automatically turned off.
For correct control media by the external temperature probe, make sure
the sensor to completely sock into the media (more than 20mm deep). If
the sensor is in the air due to evaporation of media, precise temperature
control may fails.
[Refer to Error Message]
• Hot Top Warning Indicator will illuminate if top plate temperature is over
50°C.
• For correct control media by the temperature probe, make sure the sensor to
completely sock into the media (more than 20mm deep). If the sensor is in the
air due to evaporation of media, Errors will be shown on display.
• Probe operating temperature range is Max 250°C.(B Class)
A Class: Max 400°C(Optional)
