Abstract
The body resistance measuring instrument for ion and iontophoresis purposes with resistance value read off which occurred after a specific time, during this period the resistance value stabilises itself with the time defined by the discharge period for two capacitors. Two transistors in the main circuit are activated which prevent passage of the supply current to the bridge, two relays (R, S) activated by the current in the transistors close the reading circuit. The discharge time of the capacitors is the same as the stabilising time for the body resistance. Pref. a control lamp illuminates the available time for precise reading of the resistance value and is supplied by a secondary circuit with capacitor transistor and resistance.
