APPARATUS FOR MEASURING THE CHARACTERISTICS OF A SAMPLE OF MATERIAL COMPRISING: MEANS FOR APPLYING A SERIES OF RECTANGULAR SINGLE POLARITY PULSES OF SUCCESSIVELY INCREASING AMPLITUDE TO SAID SAMPLE OF MATERIAL FOR PRODUCING A CURRENT WHICH PASSES THROUGH SAID SAMPLE, MEANS FOR RECEIVING SAID CURRENT AFTER PASSING THROUGH SAID SAMPLE AND FOR DERIVING AN OUTPUT PROPORTIONAL TO THE CURRENT FLOW THROUGH SAID SAMPLE WHICH IS RESPONSIVE TO THE SUCCESSIVELY INCREASING PULSES. DISPLAY MEANS HAVING HORIZONTAL AND VERTICAL DEFLECTION MEANS FOR SIGNAL PRESENTATION IN TWO COORDINATES, MEANS IN SAID DISPLAY MEANS FOR PRODUCING A TIME BASE SWEEP SIGNAL SYNCHRONIZED WITH THE SUCCESSIVELY INCREASING SINGLE POLARITY PULSES, MEANS FOR APPLYING THE OUTPUT SIGNAL PROPORTIONAL TO THE CURRENT FLOW THROUGH SAID SAMPLE TO SAID VERTICAL DEFLECTION MEANS OF SAID DISPLAY MEANS, AND MEANS FOR APPLYING THE SERIES OF SUCCESSIVELY INCREASING RECTANGULAR SINGLE POLARITY PULSES AND THE TIME BASE SWEEP SIGNAL TO THE HORIZONTAL DEFLECTION MEANS OF SAID DISPLAY MEANS.
