Performance Analysis of Automatic SPRT Module Calibration

Main Article Content

This paper aims to present a performance analysis of automatic calibration system of the standard platinum resistance thermometer module. The automatic method is based on the use of low thermal matrix scanners. Calibration results obtained from the automatic technique are compared with the results gotten by the conventional manual technique. The t-test, statistic hypothesis method, is used to assess whether the results of two techniques are statistically different from each other. The paired t-test analysis results show that there is no difference at the 95% confidence level. This confirms that the automatic technique using low thermal matrix scanner can be effectively employed. Moreover, it provides several advantages such as reduced errors caused by manual operation, reduced operating time, reduced paper usage, saving in labor cost, and obtaining benefits of electronic documents.
