2
(30 mm side).
Stimulation temperature range is 0C to 55C.
Refer to section 20, page 165 to view the full range of Thermode types and
sizes.
2.3 Switching Thermodes
The software activates the proper Thermode, based on the Program chosen by the user.
No additional user intervention is required. To disable or disconnect a Thermode refer to the
Technical service manual for detailed instructions.

2.5 Terminology
The following terms are used throughout the user manual:
Table 5: Terminology
The probe which is used to apply the thermal stimulation on the subject's
skin.
Thermo Electric Cooler (TEC), a Peltier element used as the active heat
generator in the Thermode.
The active heat generator used for the CHEPS Thermode.
The Cooling Unit (referred to also as an External Cooling Unit – ECU) is a
component within the system which is responsible for refrigerating and
circulating the coolant through the system and Thermode(s).
The initial/rest temperature of the Thermode, after system initialization
and in between tests. Also referred to as Adaptation Temperature.
The initial temperature the stimulus starts from
The final temperature the stimulus ends with.
Indicates the time the probe will remain at the destination
A short and fast stimulus specified by the baseline and destination
temperatures only. The rate is automatically set to the maximum
capability.
A set of trials with the same specifications
