Temperature Regulator Stirrer Speed Regulator
6.3 Place the required liquid in the beaker and place the beaker onto the heater platform.
Note : To get the correct temperature control during the test it might be necessary to
use a heat transfer material between the beaker and heater platform.
6.4 Turn all the controls to their minimum positions and then switch on the mains switch on
the front panel. Place the small stirrer bar into the liquid in the beaker and then, using
the stirrer control knob, adjust to a suitable speed for stirring the liquid.
