Improving High Resistance Measurements With Voltmeter And Ammeter Instruments High resistance measurements are integral to a variety of test applications, including surface insulation resistance (SIR) testing of printed circuit boards, resistivity measurements of insulating materials and semiconductors, and voltage coefficient testing of high ohmic value resistors. Ensuring the accuracy of high resistance measurements (i.e., resistances of 1G (109 ohms) or higher) requires the use of specific techniques and instruments, such as an electrometer, a Source-Measure Unit (SMU), or picoammeter/voltage source combination. Moreover, an electrometer can measure high resistance using either the constant-voltage or the constant-current method. Essentially, the use... Read full post here
