Operation
Note: When using any of the ceramic hotplates
(HP-200-C, ST-200-C, SHP-200-C and SHP-200D-
C) at temperatures over 180ºC, the base of any
equipment used must not make contact with
the ceramic plate outside the Hot Zone, see
figure 6. This is to avoid damage to the hotplate.
Note: Modular heating blocks are not suitable for
use with ceramic top hotplates.

Figure 6
Switch the unit on using the mains on/off switch
(see figure 2).
The control knob labelled "HEAT" on the front
panel controls the heat output and hence the
plate temperature. It is graduated with an
approximate temperature scale. This scale refers
to the temperature of the top plate and not to
the temperature of the contents of the vessel
being heated.
Turn the control knob clockwise to the required
plate temperature. As the plate heats up the LED
temperature segments around the dial will light
up in turn and their light intensity increase until
the set surface temperature is reached. Conversely
if the unit is cooling, the LED temperature
segments will go out as the plate approaches the
set temperature.
SHP-200D-C, SHP-200D-S
Switch the unit on using the mains on/off switch
(see Figure 2). When the control knob labelled
"HEAT" is pointing to the Power on/off position,
the LED display will show the word "OFF". Turn
the control knob to the required temperature
which will be shown on the LED display. The
temperature will increment in 5°C steps. A few
seconds after setting the temperature, the display
will revert to showing the actual temperature of
the hotplate.
If the unit is switched off using the mains on/off
switch while the control is in a set position, the
next time the unit is switched on the LED display
will show the word "On" followed briefly by the
previously set temperature. The display will then
revert to the actual top plate temperature and the
unit will then begin to heat to the set
temperature.
WARNING: When the surface becomes
too hot to touch the red "HOT" warning
