I. Applications and Features
XF30-G ModelMulti-functional Standard Power SupplyAn intelligent AC/DC standard voltage and current calibration instrument (with AC output displayed as true RMS). The VFD screen displays the actual output value, percentage, and output frequency, and can be calibrated according to the meter being tested.RangeSelect the full scale value and the corresponding step size. Amplitude adjustment is available.KeyboardSwitch or potentiometer control. Standard source,RangeWide range, fine gradation, high precision, good stability, easy to use, and portable. Suitable for calibration, verification, and repair of 5.5-digit digital multimeters, various pointer-style AC/DC voltage and current meters below 0.1 class; also serves as a high-stability test power source, compatible with higher-grade standard meters, for calibrating current and voltage meters above 0.05 class.
 
II. Main Functions
1: XF30-G features a 6½-digit digital display output, showing values both in actual and percentage formats simultaneously.
2: XF30-G utilizesKeyboardPotentiometers control the increase or decrease of output quantity.KeyboardControl quantities are divided into 100%/N, 10%/N, 1%/N, 0.1%/N (N stands for 4, 5, 6, 10, 15).
                      3：External Control RegulatorThe controller can adjust the output quantity remotely, featuring a regulating function.KeyboardTwo configurations available: with potentiometer.
4: AC and DC voltage output range is 0 to 1000V.
5: DC and AC current output range is 0 to 20A.
6: Available communication frequencies: 50Hz, 60Hz, 100Hz, 400Hz, 500Hz, 800Hz, 1kHzCrystal OscillatorGuarantee frequency stability or sync with utility power.
7: The 50Hz output can be set to AC mains synchronous to reduce the influence of the beat frequency on the meter under test.
Overload protection with automatic shutdown and manual reset.
