right hand corner of the display of the SCT1
temperature controller. The amber control LED
on the front panel of the hotplate will NOT be
illuminated in monitor mode.
NB: When in monitor mode, the SCT1
temperature controller operates as a digital
thermometer only, and no longer controls
the temperature of the medium in use. The
hotplate temperature can now be manually
adjusted to the desired setting.
To change from monitor mode to control
mode
To change from monitor mode to controller
mode, press either the + or – key on the SCT1
temperature controller once. The unit will revert
to controller mode, and will be indicated by the
illuminated amber control LED visible on the
front panel of the hotplate. The red LED on the
top right hand corner of the SCT1 temperature
controller display will extinguish when the unit is
in controller mode.
N.B. For safety reasons, when reverting
from monitor to controller mode the SCT1
temperature controller will default to the
set point temperature of 20°C.

In the event of malfunction the SCT1
temperature controller can self diagnose certain
fault conditions. In this case the display will show
a message in the form of 'Err XX' where XX is
either a single or double digit code, which
