Modern precision digital multimeters are sophisticated measuring instruments offering more than just the ability to measure voltage, current and resistance. More recently, a new type of precision multimeter, the Fluke 8508A Reference Multimeter, has been developed with the accuracy and stability of metrology grade instruments approaching measurement levels available from the standards used to calibrate them. Such high performance allows these multimeters to be used in place of many traditional laboratory instruments such as Kelvin-Varley dividers, null detectors, resistance bridges and even PRT (Platinum Resistance Thermometer) calibrators. Not only do metrology grade multimeters provide sufficient precision, they also bring a significant improvement in usability and throughput compared to traditional techniques—the latter being of great importance in today’s economic climate where calibration laboratories of every type are challenged to meet technical and business objectives alike. Instrumentation designers pay careful attention to maximizing the functionality of the instruments, while at the same time ensure ease of use. However, these sophisticated instruments offering comprehensive capability can appear complex to users. This application note sets out to simplify and explain how these various Fluke 8508A Reference Multimeter features can be used to maximize your lab’s efficiency.
