Unit Inspection
- Inspection of cooler thermistor (ambient sensor)
- Resistance inspection
- Measure the resistance according to the following chart.
- Resistance inspection
Resistance
| Inspection terminals | Inspection conditions (Ambient temperature) | Standard value |
|---|---|---|
| 1 - 2 | 10°C {50°F} | 3.00 to 3.73 kΩ |
| 15°C {59°F} | 2.45 to 2.88 kΩ | |
| 20°C {68°F} | 1.95 to 2.30 kΩ | |
| 25°C {77°F} | 1.60 to 1.80 kΩ | |
| 30°C {86°F} | 1.28 to 1.47 kΩ | |
| 35°C {95°F} | 1.00 to 1.22 kΩ | |
| 40°C {104°F} | 0.80 to 1.00 kΩ | |
| 45°C {113°F} | 0.65 to 0.85 kΩ | |
| 50°C {122°F} | 0.50 to 0.70 kΩ | |
| 55°C {131°F} | 0.44 to 0.60 kΩ | |
| 60°C {140°F} | 0.36 to 0.50 kΩ |
NOTE:
- If you touch the temperature sensor, correct judgment cannot be made due to your body temperature. To inspect the sensor, hold the connector side.
- Perform inspection after the sensor is adapted to the ambient temperature.
