I. Usage and Features:
The XF30DA AC Current Calibrator is an intelligent current calibrator. It features three simultaneous displays for the output actual value, percentage, and the meter's full scale value. You can set the meter's full scale value and select the corresponding step size based on the meter's scale. Amplitude adjustment options are available.Keyboard(Digitally controlled or potentiometer controlled) with digital display, error direct reading,RangeWide range, fine gradation, high precision, excellent stability, and ease of use. Suitable for calibrating, verifying, and repairing AC ammeters below 0.5 class; also serves as a high-stability test power source when paired with high-grade standard meters, for checking 0.2 class AC ammeters.
II. Main Functions:
5 1/2-digit LED digital display with simultaneous display of actual value and percentage.
2: UtilizeKeyboardControl the increase and decrease of output volume.KeyboardControl quantities are divided into 100%/N, 10%/N, 1%/N, 0.1%/N (N represents 4, 5, 6, 10, 15).
