I. Features:
XF30A* ModelMulti-functional Calibration InstrumentIt is an intelligent AC/DC standard voltage and current calibrator (with AC output displaying true RMS value). The three windows simultaneously display the actual output value, percentage, and the full scale value of the tested meter. The full scale value of the tested meter can be set, and the corresponding step value can be selected according to the scale of the tested meter. Amplitude adjustment options are available.KeyboardPush-button or potentiometer control. Features digital display, error direct reading,RangeWide range, fine gradation, high precision, good stability, and easy to use. Suitable for calibration, verification, and repair of 4.5-digit multi-meters, various 0.2 and 0.5 class below pointer-type AC and DC voltage and current meters; also can be used as a high-stability test power supply, paired with high-grade standard meters for calibration of 0.1 class current and voltage meters.
II. Main Functions:
1:5 1/2-digit LED digital display for output quantity, showing both actual value and percentage simultaneously.
2: UtilizeKeyboardControl the increase or decrease in output quantity.KeyboardControl quantities are 100%/N, 10%/N, 1%/N, 0.1%/N (N represents 4, 5, 6, 10, 15).
3：External Control RegulatorThe controller allows for off-line adjustment of output quantity increase or decrease.KeyboardAvailable in two configurations with potentiometers, switchable at will.
4: AC and DC voltage output range is 0 to 1000V.
5: AC and DC current output range is 0 to 20A.
6: The available communication frequencies include four options: 50Hz, 60Hz (59.7Hz), 400Hz, and 1kHz.Crystal OscillatorGuarantee frequency stability.
7: Overload protection with automatic shutdown and manual reset.
8: The 50Hz output can also be synchronized with the mains power to minimize the impact of beat frequency on the meter under test.
Clamp Meter Measurement: Equipped with our standard coil, capable of measuring 0～1000A current with an accuracy of ±0.3%.
