Abstract
Easy auto-measurements are introduced for student experiments and undergraduate researches, for example, a thermocouple, an audio tube amplifier, etc. Digital instruments are often used instead of analog ones nowadays. Then many measurements are carried out automatically. Auto-measurements reduce measuring time, human load and errors. They are helpful for student experiments, because students are able to have enough time to check their measuring results, and then to carry out their experiments again. Auto-measurements require software. It is usually hard to prepare measuring programs. However, it is not hard for student experiments of measuring volt, current and so on. If program modules for GPIB or RS-232C are used, their measuring programs become easy and small in size. The author taught students to prepare measuring programs using Excel VBA with their program modules. Many students had little programming experience, but they were able to prepare and use them for their experiments.
