XL-847C DC Transformer Tester Overall Calibration Device, used for error calibration of DC transformer testers with analog input based on FT3 input.
Product Description
Product Introduction
XL-847C DC Transformer Tester Overall Calibration Device ， Used for based on FT3 Error calibration of DC transformer tester with analog input of DC transformer tester 。
Features
- Calibrate the ratio error of DC transformer tester.
- Calibrate the ratio error of small signal DC transformer tester.
- Calibrate the ratio error of DC transformer tester based on small signal input standard.
- Using standard DC analog source and standard DC digital source output methods, when calibrating digital DC transformer testers, digital micro-differences can be superimposed on the standard DC digital source. Used to verify the DC transformer tester's error detection capability.
- Internally uses a highly stable standard DC analog source, capable of outputting high-accuracy DC voltage, DC current, and small DC voltage signals.
- When superimposing digital micro-differences, based on the FT3 protocol characteristics, a reference value fine-tuning method is used to make the actual digital and analog micro-differences consistent with the set micro-difference value. This solves the numerical quantization problem caused by relative value representation in protocols like FT3.
