Measure a resistance of NTC and Heated pad.
1. NTC resistance - 10.0 kΩ ± 10% (25°C)
2. Heated pad resistance - 1.88 Ω ± 10%
Measure a temperature.
1. The temperature of wheel surface grip must rise from -20°C to 20°C within 6 minute
2. The temperature of wheel surface grip must keep 38°C ± 4°C after 25 minute
3. At that time switch on, all measure point (1~8)
