3894532 is referenced by 124 patents and cites 9 patents.

Instrument provides three modes of operation: (1) An impedance measuring probe and meter and a tone generator, the frequency of which is a function of the skin impedance at the test point. A squelch circuit disables the tone generator when the probe is not in contact with the skin; (2) A sensitive voltage measuring meter can then be switched on using the same indicator. The polarity of the voltage at the probe is indicated by differently colored lights; (3) A voltage generator can then be switched on to provide bursts of electrical energy to the test point. Multiple electrodes are also provided.
