☆ Special Test Software (optional)

TD1880 Precision Multifunction Calibrator Special Test Software

The measurement and calibration workload of digital meters and analog meters is huge, and the measurement standards are relatively complicated. However, the human interference factors of traditional manual measurement are relatively large, the reliability of calibration results is not high enough, and the efficiency of measurement and calibration is low.
Users can choose the special calibration software independently developed by TUNKIA, which supports fully automatic or semi-automatic calibration of the tested equipment, raw data recording, analysis, management and export of customized template reports. Compared with traditional manual calibration, it has obvious advantages, effectively solving various inconveniences of manual manual calibration, and significantly improving work efficiency.

(Note: During automatic calibration, the tested equipment should have communication function and open communication protocol to realize data reading)
