Press ‘up’ or ‘down’ arrows keys to increase or to reduce the Set Point
Temperature while it is flashing.
Press ‘Enter’ to confirm the new Set Point temperature.
Go to the Sub Menu ‘Offset’ and change the actual Reading Offset of BASE, LID and HM
temperatures, in order to have the sample at the set point temperature, as described below.
Use table
From the main menu press the ‘Menu’ key on the front panel.
Move the cursor to ‘Offset’ with the ‘up’ and ‘down’ arrow keys.
Press ‘Enter’ with the cursor on the item ‘Offset’.
Move the cursor to the item ‘Base’ using the ‘up’ and ‘down’ arrow keys.
Press ‘Enter’ to change the Reading Offset of Base temperature.
Press ‘up’ or ‘down’ arrow keys to increase or reduce the Reading Offset of Base
temperature while it is flashing.
Press ‘Enter’ to confirm the new Reading Offset of Base temperature.
Move the cursor to the item ‘Lid’ with the ‘up’ and ‘down’ arrow keys.
Press ‘Enter’ to change the Reading Offset of Lid temperature.
Tip
►
Set the Offset of the Lid at a value higher than the Offset of the Base by 2°C. Eg. If
offset of the Base is +5°C then set offset of Lid to +7°C. As a result the Lid will be at a
temperature 2°C higher than the Base. This is done to avoid water condensation on the
observation window. With these assumptions the ONLY parameter that needs to be
experimentally identified is the Reading Offset of Base.
Press ‘up’ or ‘down’ arrows button to increase or to reduce the Reading Offset of
Lid temperature while it is flashing.
Press ‘Enter’ to confirm the new Reading Offset of Lid temperature.
Press ‘Menu’ Key to exit from the Sub Menu. Press ‘Menu’ key to go to the Main
Page.
Wait until the steady state of the Free Sensor temperature is reached.
Increase the Reading Offset of Base and consequently the Reading offset of Lid,
if the temperature of the Free Sensor at steady state is lower than 37.0°C.
Table 3 shows Offsets measured at the factory with an insert for a single 35mm dish and a set
point of 37°C. Additional Offsets for set points other than 37°C were extrapolated.
