NOTICE
The heated lid automatically switches off at a temperature difference of >75 °C be-
tween the block and the heated lid. At these low block temperatures, sample conden-
sation on the tube lid is no longer to be expected. In addition, it supports a longer
service life of the Peltier elements in the block, since no unnecessary cooling against
the heating cover is required.
7.5 Set preheating mode
The heated lid can be set to preheating ON or OFF using the corresponding buttons:
If the preheating mode is activated the heated lid is heated up to the target tempera-
ture while the sample block is held constant at 25°C. After the heated lid reaches the
target temperature a 40 seconds equilibration phase follows. Then the sample block
starts to heat up from 25°C to the first programmed temperature.
Note: For most applications it is recommendable to set the preheating function to ON.
