きない場合もある。However, when data transmission is performed using this slip ring, there is a problem in that the S/N ratio deteriorates due to contact noise. In order to avoid this problem, there is a method of transmitting data using a wireless telemeter, but this method has the disadvantage that the data transmission system is complicated and costs are high. Moreover, there are cases where the telemeter device cannot be used during the spin test.
