voltages at low-error current levels in connection with an external voltmeter with an internal resistance exceeding 3 kΩ and a range between 0.3 V and 3 V (10 V max.), for example demonstration moving-coil instrument (531 900), and TY or XY plotters. Including BNC-4-mm cable (575 24).Examples of applications:Proving the existence of electrostatic induction chargesMeasurement of very large resistancesEquipotential lines of electrical fields in weakly-conducting liquidsCapacitance measurementsVerifying the piezoelectric effectDemonstrating the photoelectric effect
