4. Resistance Law, Linear Deviation: During the whole journey, the resistance law changes into a linear law,
    the  linear deviation is not (+10%).
5. The rheostat control shaft should rotate for 5000 weeks in no less than 90% of the journey. There should be
     no visible damage to the rheostat.
6. The resistance of the rheostat is less than 1.5 after 6 weeks (six days) of alternating humidity and heat at
    40℃ at high temperature.
