? HIGH PRECISION---The input and output signal could be generated simultaneously with high precision, showing you the precise data of input and output current, voltage, frequency, etc ? REAL-TIME CURVE---The input/output changing can be displayed as curves, so that it is easy to know the changing tendency, helping to improve your work efficiency ? ULTRA-CLEAR DISPLAY---With the ultra-clear display, the reading of the signal generator calibration could be read clearly even in the sun, allowing you to work in various conditions ? SILICONE BACKLIGHT BUTTONS---With silicone backlight buttons, the signal generator calibration is of trouble-free operation in darkness, convenient to use ? WIDE USAGE---The signal generator calibration could be widely used in industrial PLC, regulating valves, process instrumentation debugging, etc
