XF30 Multi functional calibratorDetailed product description：

Purpose and characteristics
The XF30 multifunctional calibrator is an intelligent AC and DC standard voltage and current calibrator. (Among them, the communication output is true RMS display) has the characteristics of digital display, error direct reading, wide range, fine grading, high accuracy, good stability, convenient use, and easy portability. Suitable for calibration, verification, and repair of four and a half digit multimeters, various pointer type AC and DC voltage and current meters below level 0.5; It can also be used as a high stability testing power supply, in conjunction with high-level standard meters, to calibrate 0.1 level current and voltage meters.  

Main functions
Five and a half digit LED digital display output, which can be displayed in two ways: actual value or percentage.  
Use keyboard to control the increase or decrease of output volume. The keyboard is divided into 10%, 1%, 0.1%, and 0.01%. The accuracy of adjustment is 0.01% of the full scale; The calibrator has a constant voltage and constant current output effect.  
External control adjustment can increase or decrease the output of off machine control.  
The output range of AC and DC voltage is 0-1000V, divided into 11 ranges.  
The output range of AC and DC current is 0-10A, divided into 15 ranges.  
There are three AC frequencies available for selection: 50Hz, 60Hz, and 400Hz (with crystal oscillator to ensure frequency stability).  
Output overload can be automatically protected and manually reset.  
AC 50Hz output can also choose mains synchronization to reduce the impact of the frequency of the tested meter.
