XF3000 AC/DC meter calibratorDetailed product description：

The XF3000 AC/DC meter calibrator is a device designed according to national standards and regulations for AC/DC meter inspection. It does not require an external standard meter and can automatically or manually calibrate single-phase and three-phase AC/DC voltmeters, AC/DC ammeters, power meters, energy meters, power factor meters, frequency meters, and phase meters at or below level 0.5, reaching the national advanced level.

Main characteristics
High precision voltage stabilization and multifunctional standard meter integration, easy to operate.  
Voltage and current output have constant voltage and constant current characteristics, as well as fixed frequency and phase functions.  
Separate DC output from AC output.  
It has automatic protection function for output voltage short circuit and current open circuit.  
By using programming to verify the electricity meter, errors can be directly displayed and test results can be stored and printed.  
Equipped with external calibration function.
