A constant current function generator is a type of electronic device that generates a variety of electrical waveforms with a constant current output. It is typically used in applications where a stable and accurate current source is required, such as in testing and calibrating electronic equipment, powering load cells and other sensors, and driving LED displays.

The specific features of the constant current function generator you mentioned (DC 12V, 24V) indicate that it is designed to operate from a DC power supply with a voltage of 12V or 24V. The generator may be capable of generating a variety of waveforms, such as sine waves, square waves, triangle waves, and sawtooth waves, with a constant current output. The exact waveform generation capabilities and other specifications of the generator will depend on the specific product.

Constant current function generators may be suitable for a variety of applications and may be used by professionals, students, or hobbyists. They may be used in a laboratory or test environment, or they may be used in the field. It is important to carefully read and follow the instructions provided with the generator to ensure proper operation and to avoid damaging the device or any connected equipment.

Power supply: DC12 ~ 30V,DC 12V or 24V, current 18mA; power port has a polarity protection.

4-bit 0.36-inch LED, the display range: -1999 ~ 9999, can be set to the number of  0,1,2,3 decimal points.
