AN AUTOMATED METHOD FOR INTERCOMPARING A GROUP OF RESISTANCE STANDARDS

H. Sakarya, L. Sozen, D. Atesalp

Abstract

To maintain the group of standards it is necessary to periodically compare the members of the group with each other and to obtain a measure of the deviation of the values of the members from the mean of the group. The mean of the group can be calculated by using a set of equations. In the national metrology institute of Turkey this work is carried out to reduce the time for calculation for the resistance measurements. The measurements are done automatically and the results are evaluated by using the computer program. By using this program, compared resistance values, history of the resistors and graph of each resistor are obtained very easily. This program can be adapted to the other group of standards i.e. mass standards, voltage standard cells, capacitance standards.
