• The resistance values are defined by below table "Thermistor resistance / temperature characteristics (type 1)":
- Resistance at 23°C: 21.85 kΩ.
- Resistance at 24°C: 20.90 kΩ.
• The measured value 21.86 kΩ is inside the range, thermistor R3T passes the check.
Table 2-1: Thermistor resistance / temperature characteristics (type 1)
Table 2-2: Thermistor resistance / temperature characteristics (type 2)
INFORMATION
The user interface allows to monitor most thermistors.
If the measured resistance of the thermistor matches the temperature measured with the contact thermometer but the
temperature for the corresponding thermistor is not correct on the user interface display, replace applicable PCB.
