Close the door of the ETHOS and start a digestion program (refer to the Milestone cookbook).
INFRARED SENSOR (option)
(p/n IRT0500)
Infrared sensor is monitoring the external temperature in all vessels.
If the TEMP-SURE option is not installed during the ramping time, due to the thickness of the
safety shields and TFM vessel, it is difficult to have a direct correlation between T
1
(internal sensor)
and T
2
(external sensor). The external temperature is in accordance with the internal at the
equilibrium (holding time), higher is T
1
(internal sensor) higher will be T
2
(external sensor).
According to our experience Milestone suggests to set the following MAX value for T2 (infrared
sensor):
Rotor T
2
HPR (SK-10) (T1 /2)+10
MPR (SK-12) (T1 /2)+20
PRO-16/24 (T1 /2)+30
Multiprep 41 (T1 /2)+30
Nova-8 (T1 /2)+50
Example of T
2
limit:
HPR T
2
=
(180°C/2)+10=100°C
MPR T
2
= (180°C/2)+20=110°C
PRO16-24 T
2
= (180°C/2)+30=120°C
Multiprep T
2
= (180°C/2)+40=130°C
*Nova-8 T
2
= (260°C/2)+50=180°C
* In the case of the Nova-8 the T2 can be slightly higher due to the long run.
