Abstract:
National Measurement Standards Laboratory (NMSL), also known as NML-SIRIM, has designed and developed a prototype of a new calibration system for timing devices with seven-segment LCD. The system uses colour mark sensor and dual counters, which operates based on a new calibration technique. To evaluate the performance of the calibration system and technique used, a bilateral comparison was organized with the Dutch Metrology Institute of the Netherlands, also known as VSL. The comparison protocol, traveling standards and results evaluation were all prepared and done by VSL. The results of the bi-lateral comparisons demonstrated that the proposed technique based on the developed calibration system has its own merits and offered accuracy that is comparable to the time base calibration system.
