OPERATION
Preparation
1. The heater design, temperature sensor and control circuit give good temperature control
and uniformity, but make sure that there is a close fit of the probes in the block to allow
efficient heat transfer.
3. Plug the power cable into the socket in the back of the unit. Connect the power cable to the
electricity supply to the mains cable.
Setting the operating temperature
1. Ensure that the heater is switched off. The ON/OFF button should be in the out position not
the latched position. The temperature can be set while the heater is on but the unit will try
to follow the set temperature as it is changed.
2. To set the temperature required, press and hold the star button, *, while pressing the up
arrow,
, or down arrow,
, button.
3. When you have the correct temperature displayed, release the star button, *, and the
actual temperature of the block will be displayed.
4. When you are ready, press the heater ON/OFF button. The heater (and heater indicator)
comes on if the set temperature is higher than the current block temperature. The
temperature displayed will increase until it reaches the set temperature.
5. Allow the temperature to stabilise and calibrate your probe.
6. The controller is factory pre-set and only the set-temperature can be changed.
After use
1. When you have finished calibrating, remember that parts of the unit and the probe may be
very hot. Take the precautions listed on page 4.
2. Switch off the heater by pressing and releasing the ON/OFF button. This will allow the fan
to cool the block near to ambient.
