On the basis of published works devoted to probe measurements 
in an ion-ion plasma, we consider the possibility of using the theory 
of orbital motion to find the parameters of a low-temperature ion-ion 
plasma. We discuss the problem of overestimating the temperature of 
the ions, which is determined by the method of taking logarithms of 
the second derivative of the volt-ampere characteristic. A comparison 
is made with results of measurements performed by the theory of orbital 
motion for cylindrical probes.
