22, 16 Fig. 17 shows states when Graph R(t) is enabled. After taking a measurement, you can switch back and forth between numerical mode display and graphical mode display by pressing h or i keys. h Graphical mode i Numerical mode Note: • It is not possible to switch the mode of presentation…

14, 8 Riss1 and Riss2 - the surface resistivity (position of optional guard connection) Riso – the actual insulation resistance of material Ciso – capacitance of material Cpi, Rpi - represents polarization effects. Fig. 8 shows typical currents for that circuit. Itest = overall …
