Test application of ATS-2420V high-precision voltage source in data acquisition and processing

发布:2020-12-08

Experiment name: Elevator safety circuit voltage data collection

Research direction: data acquisition and processing

Experiment content:

Use high-precision voltage source to calibrate the data acquisition channel parameters of the data acquisition board

Test purpose:

 to calibrate the data acquisition channel parameters of the data acquisition board

Test equipment: ATS-2420V voltage source

experiment procedure:

Using high-precision voltage source as the adjustable reference source, calibration value setting: 1.000V, equipment acquisition corresponding voltage value 0.956; calibration value setting: 10.000V, equipment acquisition corresponding voltage value 9.950; calibration value setting: 10.000V, equipment acquisition Corresponding voltage value is 99.910; use the least square method to perform linear regression processing on the three sets of data to obtain the fitted straight line: y = 0.999x + 0.042, and import the calibrated parameter compensation equation to the device in a program.

Test Results:

Test and verify the calibrated equipment again, using the voltage source as the adjustable reference source, and set the voltages as: 1.000V, 2.000V, 5.000V, 10.000V, 20.000V, 30.000V, 40.000V, 50.000V, 60.000V , Test the corresponding set voltage, the deviation between the equipment test result and the voltage reference source is better than 1%;图片2.png

The performance of the high-precision voltage source in this experiment: quickly calibrate the channel parameters of the data acquisition board

The reason why you choose this voltage source: High-precision data calibration, convenient, fast and effective
