I. Application and Features:
XF30DQ modelMulti-functional Calibration InstrumentIt is an intelligent AC and DC standard voltage and current calibrator. (The AC output displays true RMS value.) The three windows simultaneously display the actual output value, percentage, and the full-scale value of the meter under test. The full-scale value of the meter under test can be set, and the corresponding step size can be selected according to the scale of the meter under test. Amplitude adjustment options are available.KeyboardPushbutton 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 multimeters, various 0.2 and 0.5 class below pointer-type AC and DC voltage and current meters; also serves as a high-stability test power supply, compatible with high-grade standard meters, for calibrating 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: UtilizedKeyboardControl the increase and decrease of output volume.KeyboardControl quantities are divided into 100% /N, 10% /N, 1% /N, 0.1% /N (where N is 4, 5, 6, 10, 15).
3：External Control RegulatorThe controller allows for off-line adjustment of output quantity increments.KeyboardTwo configurations available, switchable at will.
4: AC and DC voltage output range is 0 to 1050V.
5: AC/DC current output range is 0~60A.
6: Available communication frequencies include four options: 50Hz, 60Hz (59.7Hz), 400Hz, and 1kHz (for use)Crystal OscillatorGuarantee frequency stability.
7: Overload protection with automatic shutdown and manual reset.
8: The 50Hz output can also be synchronized with the municipal power supply to minimize the influence of beat frequency on the meter under test.
9: Clamp Meter Measurement: Equipped with our standard coil, capable of measuring 0～1000A current with an accuracy of ±0.3%.
