Figure 13. Chamber Mode Setting
In this configuration the temperatures of both the lid and the base of the incubating chamber are strictly
controlled. A careful calibration performed in our laboratories between these temperatures and that of the
sample, guarantees that sample temperature is maintained at the desired set point value. The advantage
of this solution is that you don’t have to manually
place the Fine Gauge Thermocouple into a Reference
Well.
Tip
►
Advantages of this Control Mode are: fast experiment start up and no specific action required in multi
user applications. The disadvantage is that it needs calibration in case of room temperature variations
/- 1 degree Celsius.
When selecting Chamber Feedback Mode the following Screen will appear:
Figure 14. Chamber calibration start
It states that the system has been calibrated at the factory at a Room Temperature of 23°C. In case your
Room Temperature, measured by the included thermistor, is different from 23°C (i.e. 20.3°C) you have 3
options:
1.
Use
Current
Calibration: this means recalling the last saved calibration settings. Once you calibrate
the system (see point 3 below) these settings will be automatically stored. The system saves only
the last calibration performed. Please note that calibration depends on i) set-point temperature; ii)
room temperature; iii) type of sample adapter in use. Hence u
sing ‘Custom Calibration’ is NOT
recommended in any of the following as it will yield inaccurate results:
A.
If the recalled calibration was performed with a different sample adapter than what you intend
to use
B.
If the room temperature on the Custom Calibration is significantly different than the current one
(i.e. more than 1°C)
