Keithley High Resistance Meter (Model – 2420 Source meter with 2182A Nanovoltmeter)
is used for the electrical characterization of the conducting/semiconducting thin films. The built-in voltage source simplifies determining the relationship between an insulator’s resistivity and the level of source voltage used. It is well suited for capacitor leakage and insulation resistance measurements, tests of the surface insulation resistance of printed circuit boards, voltage coefficient testing of resistors, gas sensing studies, solar cells studies and diode leakage characterization. Instrument is provided with 2 probe and 4 probe set up for electrical measurements.
