XF30DA AC current calibratorDetailed product description：

The XF30DA AC current calibrator is an intelligent current calibrator. Three windows simultaneously display the output actual value, percentage, and checked table full value. It is possible to set the full-scale value of the inspected table and select the corresponding step size based on the scale of the inspected table. The amplitude adjustment can be controlled by keyboard (key) or potentiometer. It has the characteristics of digital display, error direct reading, wide range, fine grading, high accuracy, good stability, and easy use. Suitable for verifying, calibrating, and repairing AC ammeters below level 0.5, and can also be used as a high stability testing power supply, in conjunction with high-level standard meters, to calibrate AC ammeters at level 0.2. Main function: 5 1/2 digit LED digital display output, displaying both actual value and percentage simultaneously; Use keyboard to control the increase or decrease of output volume. 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 there are two configurations on the regulator: keyboard and potentiometer, which can be converted freely; The output range of AC current is 0-300A; there are five AC frequencies to choose from: 50Hz, 60Hz (59.7Hz), 400Hz, 1kHz, Fx (10kHz); Output overload can be automatically protected and manually reset.
