Three temperature control ranges are available:
TRN = 0-100 °C,
TRM = 0-200 °C,
TRH = 0-250 °C.
The desired operating temperature can be
set using the control knob with its graduated
scale. The control function is displayed by
LED. A clear cover shows the set value and
the switch function, thus ensuring that the
desired value has not been changed unattended.
