This instrument uses multiple calculations and functions to implement, and performs automatic Zero calibration and temperature coefficient compensation current, voltage, temperature and other measured signals are input through the gated analog electronic switch, and are amplified to a certain amplitude and then sent to the /D converter to convert them into digital signals. The digital signals are sent to the / interface for calculation and processing. , to ensure accurate measurement values, and finally output through the LCD display. The output of the analog signal uses a high-precision digital-to-analog converter and is amplified and buffered for output.
The nonlinear and optimal cubic spline interpolation is used for data processing. Temperature compensation uses self-calibration technology and uses an LCD to display measured and set parameters. Modern signal processing technology and modern measurement theory are used to further improve measurement performance.
