Abstract

Resistivity is an important in any material that conduct an electricity as it enables the right materials to be used in the right places in the electrical components. Resistivity can define as the measured of resistance that across a material and it is determined based on the physical dimensions of the material. The resistivity of a material depends on a several factors, such as applied voltage, electrification time and environmental condition such as temperature and humidity. Most of the electrical resistivity measurement is used as a quality control test. In order to determine the resistivity of a material, the uncertainty of measurement was introduced. The purpose of this measurement uncertainty is to determine the range of the possible value can vary within the true value of the measurement lies. The uncertainty of measurement is the doubt that exists in the result of many measurements. The quantitative measurements are performed each day and the role of measurement uncertainty becomes more important while accessing to the conformity. Measurement uncertainty is critical to risk assessment and decision making. Some of the decision make based on the reports that containing the quantitative measurement data. As according to the National Institute of Standards and Technology, no measurement that complete without accompanying statement of the associated amount of the uncertainty. In this research paper, both of surface and volume resistivity was conducted on Monroe Electronic Model 272A. There are two types of material with three sample specimen of material itself were tested and analyzed in order to determine the measurement uncertainty of the equipment. Therefore, the purpose of this research is to improve the quality of the measurement of surface and volume resistivity equipment by analyzing the measurement of uncertainty of surface and volume resistivity equipment
