1.5 System Protection

1.5.1 System Self-Test

Upon start-up the system performs a self-test in which system sensors are being tested. If a
malfunction is detected, an appropriate message is displayed and the system cannot operate until
that malfunction is resolved.

1.5.2 Temperature Safety Mechanisms

Several safeguard mechanisms have been implemented in the system to safeguard against
extreme temperatures and to protect the tested subject and the unit.

Software protection mechanisms include:
 Temperature upper and lower limits – In normal operation, Thermode temperature will always

be within these limits.

 Time duration limits – Thermode temperature is limited in duration. If the Thermode

temperature maintains a specific temperature (or above) for a longer period of time then
specified for that temperature, the system will go into Safe Mode.

 Safe Mode – a protective state of the system in which it is not possible to run tests. In any case

of suspected malfunction or if any modification is made to system hardware settings, system

will remain in safe mode until a system Self-Test is performed.
Hardware protection mechanisms include:
 If the Thermode temperature reaches 57C an analog circuit overrides the system and lowers

the temperature gradually.

3 Thermode Calibration

Thermode calibration is specific to Thermode and System. Therefore calibration tables can’t be
shared between Thermode and/or Q-Sense systems. Calibration must be performed for each
Thermode and System separately.

The calibration procedure must be performed using the Calibration kit supplied by Medoc and
Medoc Main Station software.

Calibration may only be performed by a trained person, and only by using
the Thermal Calibration Kit supplied by Medoc.

3.1 Thermode Calibration Overview

 Thermode Calibration refers to the process of assigning a temperature with the digital input

received from the temperature sensors.
 Calibration table consist of 30 temperature points. During calibration each temperature point is

assigned two ADC values referring to the calibrated measures according to Thermode type. All

values (ADC and temperatures) can be monotonically increasing only.
 The calibrated measures in Q-sense Thermodes are two thermistors. Their ADC values are

referred to as TEC 1 and TEC 2.
