XF30G Type Multi functional Standard SourceDetailed product description：

Purpose and characteristics
The XF30G multifunctional standard source is an intelligent AC and DC standard voltage and current calibrator. (The communication output is displayed as true significant value). The VFD screen displays the actual output value, percentage, and output frequency, and can select the full-scale value and corresponding step size based on the range and scale of the tested meter. The amplitude adjustment can be controlled by keyboard (key) or potentiometer. Standard source, wide range, fine grading, high accuracy, good stability, easy to use, and easy to carry. Suitable for calibration, verification, and repair of five and a half digit multimeters, various pointer type AC and DC voltage and current meters below 0.1 level; It can also be used as a high stability testing power supply, in conjunction with higher-level standard meters, to calibrate current and voltage meters above level 0.05.

Main functions
The output quantity is displayed as a 6 and a half digit number, with both actual value and percentage displayed simultaneously.
Use a keyboard or potentiometer to control the increase or decrease of output. The keyboard control quantity is divided into 100%/N, 10%/N, 1%/N, and 0.1%/N (N is 4, 5, 6, 10, 15).
The external control regulator can control the increase or decrease of output quantity off the machine, and the regulator has two configurations: keyboard and potentiometer.
The output range of AC and DC voltage is 0-1000V.
The output range of AC and DC current is 0-20A.
The available AC frequencies are 50Hz, 60Hz, 100Hz, 400Hz, 500Hz, 800Hz, 1kHz (with crystal oscillator to ensure frequency stability) or mains synchronization.
AC 50Hz output can be synchronized with the mains power to reduce the frequency impact of the tested meter.
Output overload can be automatically protected and manually reset.
