Tube temperature
NOTE: It takes approximately 50 minutes for the interior of the hybridisation
tubes to reach the displayed temperature depending upon the number of filters and
amount of hybridisation fluid used.
Power Indicator
The top indicator shows that there is power to the unit
Heater Indicator
The next indicator shows when the heater is heating the unit. When the
temperature is being set, and the new set temperature is higher than the temperature
already in the unit, the heater indicator will light as the unit tries to follow the set
temperature. If the light is on continuously the heater is getting constant power. The
only exception is described under Over-Temperature Indicator. As the temperature
approaches the set temperature the heater indicator will flash. When set temperature
is reached the indicator will stay on for shorter periods. If the oven is above the set
temperature then the indicator will be off, as the heater is not getting any power.
Over-Temperature Indicator
If the unit should, for any reason, exceed the temperature set for the over-
temperature cutout, the over-temperature indicator will light. The heater will have been
switched off and the unit will begin to cool even if the heater light is on (the light staying
on or not depends on which circuit has sensed an over-temperature). The fan will
continue to circulate the air.
