The 8100 series is designed for development labs and manufacturers who need to measure a wide variety of parameters with an accuracy of up to 4 ppm. An extremely low quiescent current at the DC inputs minimizes errors when used for zeroing in conjunction with resistor dividers. The high input impedance of the AC input, up to 10 V, further reduces errors when measuring current with shunts. This allows the 8100 series to perform reliable measurements across multiple functions. Dynamic display of accuracy, measurement uncertainty, standard deviation, and other parameters provides users with immediate feedback on their measurements. The 8100 series offers very wide input ranges. For example, currents up to 30 A can be measured without external shunts, and a dedicated, low-noise electrometer input is also available. Optimized for use with Transmille AC/DC current shunts, the 8100 series allows input of DC and offset parameters so that the measured current can be displayed directly on the screen. The series simultaneously measures voltage and frequency and performs a real-time correlation based on the difference between AC and DC at the current frequency and the resistance of the shunt. The high input impedance of the 8100 series, below 10 VAC, eliminates the need for buffer amplifiers, minimizing potential sources of error and simplifying connection. As with all Transmille products, compatibility with ProCal calibration software is guaranteed.
These high-impedance components are available in the 8100 series below 10 VAC, eliminating the need for buffer amplifiers and thus minimizing potential sources of error and simplifying connection.
