Profile:

The KDGK-703S is a high-precision calibrator that integrates AC/DC voltage, current, and resistance output functions. It uses a 7-inch TFT touchscreen and digital closed-loop control to deliver stable, accurate signals for instrument calibration. With a compact design and intuitive operation, it is an essential tool for metrology and quality control.

Features:

  • 7-inch touchscreen interface: 800×480 resolution for clear parameter display and easy operation
  • Multi-function output: AC/DC voltage, current, and resistance in one instrument
  • Precise adjustment: Step adjustment (N=2,3,4,5,6,8,10,15) and cursor fine-tuning for accurate setting
  • Clamp meter calibration: Supports 0~1000A clamp meter testing with 1000A clamp-on calibration coil
  • High stability:
    • DC: ≤±0.05% accuracy, temperature coefficient ≤0.002%/°C
    • AC: ≤±0.1% accuracy, frequency ≤0.1% (50/60/400Hz)
  • Safety design: Plug-in compensation terminals and overload protection
  • Wide compatibility: Calibrates 0.1-level ammeters/voltmeters and precision multimeters
