Power Indicator - Techne Tecal 140S Manual De Instrucciones

The DOWN ARROW Button
When the SET temperature button is held down and the DOWN ARROW
button is pressed, the set temperature is decreased.
Speed of Change of Set Temperature
Each press of the UP ARROW or DOWN ARROW buttons will increase or
decrease the set temperature by 0.1°C. If the buttons are held down the
temperature change will accelerate to 5° per second

Power Indicator

The top indicator shows that there is power to the unit
Power to the Block Indicator
The next indicator shows when there is power to the block.
When the set temperature is different to the block temperature this indicator
will light. If the light is on continuously the block is getting constant power.
The only exception is described under Over-Temperature Indicator. As the
temperature approaches the set temperature the indicator will flash. When
set temperature is reached the indicator will stay on for shorter periods.
Sensor fault Indicator
If there should, for any reason, be a sensor fault, the bottom indicator will
light. The power to the block will have been switched off and the unit will
begin to return to ambient even if the power light is on (the light staying on or
not depends on which circuit has sensed a fault).
