Discussion on the calibration method of DC digital potentiometers
DC digital potentiometers is the updated product of traditional DC Potentiometersis.It can di-rectly output or measure DC millivolt signals and current signals.It is often used to calibrate various mod-els of transmitters and thermocouples.However,there is no national technical specification for the tracea-bility method of DC digital Potentiometersis.This article analyzes the measurement characteristics,cali-bration conditions,calibration methods,and other aspects to explore the solution to the traceability prob-lem of DC digital potentiometers.
