- Abstract:
- This paper describes the development, under a graphical programming environment, of a software application to control a modified Wheatstone bridge for measurement and calibration of high value standard resistors. Intuitive panels allow an easy user interface to control the bridge (three high performance measurement equipment and a variable DC voltage source), through a GPIB bus and on screen indications to all non-automatic operations. The user can graphically preview the intermediate results and decide to accept or refuse the data. The data can then be used to calculate the temperature and humidity coefficients, and determine the final result along with the correspondent expanded uncertainty from a set of values for each calibration point. A database can be maintained for each resistor standard with this data.
