Combined device `` Ts-39 ''.
Instruments for adjusting and controlling the PTA.The combined device "Ts-39" (volt-betaammeter) has been produced since 1969. It is designed to measure the strength and voltage of a direct current, the effective value of the sinusoidal AC voltage, DC resistance, as well as indication of the parameters of low-power transistors by the initial collector current and the gain at the given circuit parameters.
